This is a hard one because there is no “right” answer and a lot of it depends on preference and budget.
I went through a similar thing about 2 years ago, at that stage I was using some free software (Amplitube), and found that it was going to be cheaper and better than to get a Fender GTX50 modelling amp rather than just buy software and then buy pedals to control it. Here is the thread from the time: Help me choose my next bit of gear - pedals?
Now, I still run a similar setup to that but have the Fender TMP doing the modelling, using either my PC with studio monitors or GTX50 as a cab. The guitar amp sounds better than studio monitors when up loud btw - it’s a bigger driver.
There’s no wrong choice, but I lean towards modellers these days rather than just software, or just amps.
