With a modern floor modeler, you’re going to have a lot of choices. For someone who isn’t sure what they want from their sound, this can be a real positive. For others the abundance of choice means you end up spending too much time tweaking and not enough time actually playing. If you’ve got a good knowledge of effects and guitar amps then you’re probably going to find it a lot easier to get stuck into a complex floor modeler, but we definitely wouldn’t recommend them for a beginner guitar player.
With a floor modeler, you’re also going to need some way to monitor your sound, whether at home, at practice, or on stage. Even with a loud tube amplifier on stage, it can sometimes be difficult to battle your way through a muddy monitor mix, and playing without being able to hear yourself is a guitarist's worst nightmare. Thankfully there are some great full-range, flat response monitors (known as FRFR) purpose-built for exactly this kind of thing. The best FRFR speakers give you a completely neutral monitor mix that ensures you can always hear your painstakingly created guitar tone whether on stage or in rehearsal.
