SMT
The only compatibility issue I can think of is power dissipation, obviously lower with SMT due to package size. Rarely a problem, but something to be aware of. The hardest thing when manually soldering a SMT part is keeping the package from moving. I use a very low-tech method to hold parts in place, a tiny bit of masking tape placed over half the part. After the open pin(s) are soldered, remove the tape and solder the other half. It works well, just use a new piece of tape every 10 parts or so.
