With the exception of a free standing tripod I bought last week to hunt a treeless slough, all I use is ladder stands.
I have several, primarily Cabelas model 15 footers. They are inexpensive but don't have much of a foot platform. I compensate for this by placing the stand in the most advantageous angle in regard to the primary kill zone at that location.
There are a bunch of makes now that have a bigger bowhunter friendly platform. I think this is a very important aspect that should be taken into consideration when buying a ladder stand.
I set up so my kill zone is 20 yards or less measured from the stand platform. I like an average shot distance of around 12-15 yards. Because the shots are generally close, I like my 56" CM Hunter 56 or 58" CM H1 for this situation (I have a 52" K-Mag due for delivery any day which should be great for this as well).
That being said, I can shoot my 60" CM H2 or Kota Prairie Swift from a ladder. The extra length is just a bit of a pain and can be detrimental if you happen to have a critter near the base of the tree. If I anticipate or have to set up for a 20-25 yard shot, these longer bows get the call, though. This is exactly the type of shot I have set up with the tripod stand in the slough.
I don't have any problem shooting well from treestands. If anything, I shoot better than with both feet on the ground. After I get set up, I release a few judo points in the kill zones to get the feel for the shot. If you can hit a leaf in the kill zone, center punching a deer's vitals as it stands at the same spot should be a gimme.
The other day I had a 3 point toy buck under me for 5 minutes at about 10 yards. He needs to grow for another 4 or so years before he interests me but had he been The One, it was a chip shot as I had practiced the shot to that exact spot.
Here's a ladder stand tip. Most stands have a stabilizer bar that ties off to the tree. If your stand doesn't come with one, supplement this with a rachet strap to snug the stand/bar tight against the tree. This makes the stand much more stable, quiet, and safe...
