Welcome to the forum Fro68!
Other users will chime in here, but IMHO there are some pretty great preset collections out there to consider (and you should include Moke in your list) -- it all depends on what you are looking for.
My
700+ Naked Amps TonePack is really all the available Fractal amps dry, mono, and "naked" -- so you can hear what every one of the 259 Fractal amp models sound like "already dialed in", with several tones for each, from vintage to boutique, to moderns to cleans.
They are organized with real life amp name and paired with cabs, making it easier to find specific amps. But they are not gussied up with wet or dry effects (besides drive block) -- you choose and add your own echos, reverbs, wah, etc. You get get over 700 tones/sounds, using the Scene 1/2 switch for each preset. So that's real good place to find out what each amp sounds like/find your own favs, and covers lots of genres and styles.
It also has a "bonus" classic rock and blues TonePack that is about 40 presets that are dialed in to emulate certain artists sounds, with some especially killer tones from Jimi H's first album. Many of the preset packs out there tend to go in this direction -- trying to give you a killer U2 or Van Halen or (name a band here) sound.
So if you gravitate towards a certain genre or band sound you like, you should look into those -- post what band sounds you want to hear and others can chime in. Axe-Change is useful place to browse sounds (for free!) but can be inconsistent -- usually the levels of user-created presets are all over the place, so you have to be ready to turn the level down fast.
Use this forum, research your questions as you dive in -- chances are, there is already a thread post with the answers you seek somewhere, as well as some good YouTube videos out there by moderator Chris and Cooper Carter (his CreativeLive Axe-Fx class is very good primer) among others.
Have fun!
