I'd like to add that even if you do want to use SMD parts SOIC package (PIC18F2455/2550) is much easier to solder than FTDI chip in SSOP package, QFN is even more manual soldering unfriendly (I assume you don't have your own reflow owen ...)
Try writing to a thumb drive with a 4550...I used to use FTDI chips all the time .. and recently I decided to stop. I stopped when I found out that locally I can get FTDI chip for 8E and PIC18F4550 for under 7E .. so that simple truth removed FTDI chips from my order list. There is nothing FTDI can do that 18f4550 cannot (except, ok, ftdi is much smaller and use less power)

What size? I did a 100 pin 0.5mm pitch by hand...not fun. Worse still was modding a board by lifting and soldering to two adjacent pins on that thing!I'm not a fan of soldering SOIC and such myself, the best solution I've found is the Schmartboard system. Soldered a TQFP with it just fine.
Actually I was soldering to a custom PCB I had designed. I have never heard of Schmartboard, curious that it is actually reasonably priced. I do not, off hand, see the difference between the "old" and the "EZ".0.5mm, easy with the Schmartboard.
