Yikes.
Aldridge and Favors aren't in the same league as scorers. Aldridge fills two high-value roles very efficiently: as a post-up option, providing good possessions when the defense is set, when the offense breaks down/in late shot clocks, and to provide rest and space for perimeter creators and shooters; and as a floor-spacer. To date, Favors is slightly above average finishing garbage buckets and pick-and-rolls, barely adequate spotting up, and a disaster on-ball. LMA's aggregate shooting statistics (TS%, eFG) are poor because of the role he fills (and the corresponding shot type distribution).
The Synergy Sports data bears this out:

I'll break this down into three categories:
- High efficiency garbage buckets: Transition, Putbacks, Cuts (it seems most cuts are just dump-offs in the data)
- Low efficiency on-ball attempts: Isos and Post-ups
- Medium efficiency specialist big attempts: PnR Roll man and Spot-ups
1. High Efficiency Garbage Buckets (transition, putback, cut)

These are by and large hard-to-create, opportunistic buckets. Largely because LMA is used as either an on-ball post-up scorer and true floor-spacer, he gets far fewer putback and cut (dump-off) opportunities (they're pretty close in transition opportunities), as evidenced by the large frequency discrepancy - 38.1% of Favors attempts come out of transition, putbacks and cuts; only 16.5% of LMA's attempts are accounted for. Still, LMA is more efficient than Favs on garbage bucket attempts (1.29 PPP v. 1.24 PPP), even after accounting for the different shot-type distributions (1.26 v. 1.24 or 1.29 v. 1.26). Due to the opportunistic nature of these shot types, there shouldn't be much of a volume-efficiency trade-off, as there is with on-ball, PnR and spot-up opportunities which induce defensive planning/focus.
The one plus for Favors is his apparent ability to get into position for cuts (again, I'm fairly certain these are mostly dump-offs). He was second in the league in total field goal attempts off cuts (after Marcin Gortat), and ranked a decent 35th in PPP of the 93 players with 57+ field goal attempts out of cuts. I've always thought Favors had good positional awareness, and this provides some support for that conclusion. Favors is very good at being in the right place at the right time.
2. Low Efficiency On-Ball Attempts (post-up, iso)
A quick note before the stats: NBA defenses are good. When they successfully stop transition opportunities and offensive rebounds, they focus their energy on taking away open 3s and layups/dunks. A couple years ago I looked at the league-wide team SynergySports data, and this was confirmed rather emphatically. Despite league-wide efficiency of 0.8 PPP, about 43% of NBA halfcourt attempts (taking out transition and putback attempts) came out of post-ups, isos and from the pick-and-roll ball handler. Off-ball attempts, which accounted for about 57% of halfcourt attempts, were worth about 1.0 points per possession. Without belaboring the point, effective offenses require good on-ball scorers to bend defenses to create high efficiency off-ball looks and to get decent shots when the defense is set, the offense breaks down and/or the shot clock is running out.

This is one of two areas where Aldridge shines. He took the second most field goal attempts out of post-ups this season, and was still 14th in PPP among the 90 players with 55+ post-up field goal attempts. If you've got nothing going, you can give LMA the ball, and let him go to work. Favors was 72nd in PPP of 90 players with 55+ post-up field goal attempts. Both players did alright out of isos on limited attempts, many of which were likely opportunistic (only 2.4% of Favors attempts came out of isos). As is clear from the stats, Aldridge is one of the very best on-ball bigs, while Favs is solidly below average.
3. Medium Efficiency Specialist Big Attempts (PnR roll man, Spot-up)
These two shot types are listed together only because they represent the two main offensive off-ball specialist roles filled by NBA bigs. Combining the two into aggregate efficiency makes very little sense, although doing so would still favor LMA.

LMA is a very good spot-up shooter for a big, scoring 1.0 PPP on his attempts. Favors, on the other hand, is still a work-in-progress spotting up. LMA was terrible in pick-and-rolls this past season, while Favs was just a touch above average, ranking 38th in PPP of 90 players with 60+ PnR roll man field goal attempts. LMA has shown more as a shooting specialist than Favors has shown as a pick-and-roll big to date. With that said, Utah has had poor pick-and-roll ball handlers and Favors may improve as the perimeter players grow (although Favors sets poor screens IMO).
As scorers, Favors and Aldridge aren't comparable. LMA competently fills two high-value roles (floor-spacer, on-ball scorer), Favors is really just a garbage man and average-ish PnR finisher.
