Eventide IMO our the bench mark for things like reverb and delays and I'm sure CK knows that he has to compete with these guys to make the KPA have what I would class as industry standard effects etc so I'm sure this day will come as the KPA is gain strength every new FW release
I went head to head with the Eventide Space vs. the Strymon BigSky, and the Eventide Timefactor vs. the Strymon Timeline. In both situations, the Strymon's were better. Not by much, but they had a little more tweakability/range, and their algorithms seemed a little more "smooth" whereas Eventide's seemed a bit "over the top."
Otherwise, Strymon has some algorithms that Eventide doesn't have, and vice versa. Eventide certainly excels in the harmonizer department, better than anything else out there, even to this day. I'd certainly go for an H9 if I needed an all-in-one box for the guitarist that doesn't use a lot of delay or reverb, but, for the Reverb or Delay heavy guitarist, I'd choose Strymon over Eventide any day.
Of course, it's all my personal opinion, and it makes me really, really excited to see what Kemper's doing with the delays. I'd love to see how they compare to the Timeline (and, for that matter, to the Timefactor).
