(Un?)Suprisingly, I daresay that it's not a bad idea to try out tracking in craptracker first, and play around with pxtone for awhile to see which method of input you like better; tracker notation or piano roll. I started out with a piano roll based thing (FL Studio), so in order to track, I've got to mentally divide the columns into beats so I can figure out where to start and end notes.
Trackers do have the perk of awesome/unique arpegiating, portemento (note slide) and vibrato (warbling) functions built in, while pxtone doesn't have all of these (it lacks an arpegiate and a vibrato function). Fancy pants sequencers typically have all of these, but finding them is a son of a bitch. Fancy sequencers also typically cost money. Not that that will stop Anonymous from getting them, but still...
Every platform has its benefits, its downsides and its crazy quirks that you get to know and love if you use it for long enough. I must agree with >>4068 and say regardless of what you pick to make stuff with, once you find a program that you like, stick with it, learn its intracies and you'll do fine. With the technical part, at least. Inspiration - you're on your own for that one.
