Though there are no profiles of axe/helix I like in the RE (which honestly surprises me) this is not the same with the neural profiles we have on the RE.Some of these are quite good.I like them.So..I have an eye on this quad cortex.But it has to be really,really outstanding to make me think "further"..there is only a 1% chance I could change my mind on spending over 1500€ for a floorboard.
You could download free trials of neural dsp vsts and try them out, as well. I myself have been split recently about whether to get a cortex or an fm3, actually. Currently more on the fm3 side largely due to thinking the amp sims are quite spectacular.
With axe fx 3 I've nailed just about any profile I've liked best. FM3 is a bit different, due to lacking tone matching, but I've had good results nonetheless (not with fm3 but using axe fx 3 as I would fm3).
Also, I wouldn't rely too too much on what I find on RE personally. I had a helix recently and compared the friedman amp to the analog equivalent. They were quite close, closer for some settings, worse for others. I've had the same experience with axe fx amp sims over and over -- even thinking some amp sims tested were closer to the amp than my own direct profiles shot of the same rig. The profiles I had found on RE were quite lacking for me, for many reasons.
I've seen other cases as well. I'd say my experiences vary a lot at this point. But if I wasn't convinced fm3 has great amp modelling -- like really really good -- i wouldn't consider fm3 at all, certainly... Especially with all the comedic hiccups involved with that product lunch. Even now too many people are having issues that shouldn't be there at lunch even imo.
