I was wondering if anyone had any thoughts about the available higher end synth pedals available these days. I'm currently rocking an FM4 and Roland GR-30, but was thinking about investing in something with some more options. I'm kind of looking something that can get digital hardcore and rave sounds, so I can continue ripping on Nick Reinhart's style

The Boss SY-1000 looks pretty gnarly, and seems like it has enough added functionality to justify it over the Sy series options. The SY-300 also looks cool, but lacks the differentiated strings that the 6 pole GK pickups offer.
Source Audio C4 also looks pretty cool, but it looks like you absolutely need the app to access the majority of its features, which is a little disappointing. I think this one might be an obvious choice if it had a screen and a few more switches, but needing an added midi controller to access presets in a live setting is a little bit of a turn off.
The Panda Midi Future Impact seems cool, but I'm looking for something primarily for guitar and there's not a whole lot of info online for people using it on things besides bass. Perhaps one of you fine folks has a two cents or so they'd be willing to share?
Meris Enzo is alright, but I just didn't click with it when I tried it. It seems like a decent evolution of the FM4, but hard to justify the price for the functionality imo.
Is there anything I'm missing or any thoughts you might be willing to share? What big synth pedals are you using and what are you using them for?
