Versatile digital modelling amps

I'm looking for the best modelling amp on a reasonable budget. I have a broad range of playing styles but mostly blues, rock, metal, country. Everything from Mayer, SRV, Vai, Petrucci, all sorts of styles and sounds.

I've got a Marshall Code 50, it's not bad but I find you can't dial in to the kinda sounds I want, and I'm wondering what else out there is worth it. I've contemplated things like the Positive Grid, Boss Katana, and I can't tell what's best suited.

As for guitars I have a good selection of Fender USA Strat, Gibson Les Paul Traditional, PRS SE, Epiphone Sheraton, Ibanez RG, Fender USA Tele, so the guitar is not the problem so to speak.

Wondering what other options people use?

I don't have space for multiple tube or combo amps or a large pedal board which is a bit of a bummer.
