Considering mid (l.20) fodder being worth 2,5 times as much xp as low (l.5), and high (l.100) being 6,7 times better than low, and assuming that on 50 and 80 stamina gardens / dailies normal chest tiles continue giving low (normal chest graphics in loot window) or mid food (expensive chest graphics), while expensive chest tile can give both mid and high grade food (first tier daily/garden gives low/mid in normal chest tile and mid in expensive chest tile). And counting chests as 1 normal + 1 expensive in first tier, 2 normal and 1 expensive in second tier, 3 normal and 1 expensive in third tier, we'll see the rewards as such:
One clear of first tier map nets from 3,5 to 5 times worth low manyuus. Second tier gives 4,5 to 11,7. Third tier should be 5,5 to 14,2.
Now factor in stamina costs. Comparison between first and second tier dailies is pretty straightforward: you can do 2 first tier maps at the cost of one second tier, so 7 to 10 from first versus 4,5 to 11,7 from second. First tier wins hands down.
Now about third tier, hmm... Lessee, with 400 stamina you can do 5 thirds, 8 seconds or 16 firsts (and have a little more stamina to spare). So it is 56 to 80 from firsts, 36 to 93,6 from seconds and 27,5 to 71 from thirds. Eh, wart, first tier wins anyway, and third tier is worse than second? That can't be right, right?

Third tier has a chance of giving 4 chests and always 3. All 4 chests has a chance to contain lvl 100 and will at the very least contain lvl 20s.

First tier wins early on since you level fast enough with its exp efficiency. Thus you can farm more manyus in total. However, later on you will take so long time that it is no longer very efficient and thus the third tier garden wins since it gives a great deal of exp and you want to farm the 12-? maps for a chance at ampys.
