Wifi run the same frequency as the cheaper wireless units if I remember correctly, right? A bunch of pedals, along with a bunch of wireless units, plus, wifi in the places running at the same time would worry me as far as reliability.This is an important point.
Actually, wifi would be better but it requires static IP in the devices to be stable.
An example is Soundcraft Ui series digital mixers, their badly implemented wifi hotspot is a major problem.
Use cat5 cable or a static IP address for the builtin wifi and they work great.
And I'll expand on my bluetooth thing. I appreciate Roger responding. To me the benefit to bluetooth comes when digging in to these pedals capabilities without having to mess with cables. Most of the time when I've built patches in pedals with bluetooth, it's just a more pleasant experience. But I'm not the target audience for any of these technologically advanced pedals. I prefer to twiddle physical knobs and unless the interface is exceptionally intuitive, I just don't have the patience for menu diving.
BUT when I said this wasn't an apples to apples comparison, I really meant it. Eventide stuff is significantly more expensive than the majority of SA pedals. They are also physically much larger when compared to the majority of the SA stuff, so there is always a compromise you have to make. And it's obvious many people do not have my issue. I'm sure I'm in the minority.
