As both a pedal and vp4 owner, ill give you my opinion. I have two board (i could build probably two more with the other pedals i have laying around).
My main board is an h90 with a gate, two overdrives, tuner and expression pedal (i run 4 cable method since i only use amps these days). I do like the ability to turn the od off if i dont want it and i can easily adjust things on the fly (however i do very little adjusting). The board sounds great and i can easily swap overdrives when ever im in a different mood.
I also built a simple board with the VP4, expression pedal and a Suhr mico midi pedal so i can channel switch with trs or midi with all of my amps. The pros to the vp4 board is i can have one button change everything including effects and amps channel. (I really hate tap dancing). Its a simple and clean board with very little wires/cabling that sounds great and is super versatile. I think the user interface is stupid easy to use and crazy simple to edit things on the fly (better interface than the H90). I don’t notice any sound degradation to my tone (I'm pretty sensitive to that) and no latency issues either.
If the VP4 was available earlier last year i would have done that instead of the H90, i do love eventide effects and always seem to come back to them but fractal is also stellar for effects as well.
From a cost standpoint the VP4 you get more for the money. I have no need or interest in amp modeling at this point (been there done that). And the whole 4 effects at one time aren’t enough complaint is really silly, some effects you can actually get two types of effects at a time but i don’t really see the need for wanting more, just t make a new preset
