Just stumbled across this thread and it's like looking into my own brain. I actually have both the T200s and the ZX7s. I have even played the i210s for a very short amount of time. For reference, I am a 10 handicap and my strength is definitely iron striking.
Ping i210 -
First off, I'm a big Ping fan. I play a Ping driver and hybrid. I like the i210s and the idea of them is what I consider the perfect club for me. I consider them a "players forgiveness" iron where distance isn't what they're designed for (and isn't what I want). The reason I didn't keep them was they're a bit harsh feeling, not great feedback, the offset, and to me personally, they're just ugly to look at. I have been waiting, seemingly forever, for them to release an updated version that checks all the boxes. The wait continues.
Titleist T200 -
I bought these after the i210s and before the ZX7s. I REALLY like these clubs. The main thing I like about them is the consistency. With other clubs in the past (i.e. JPX 919F), I'd get the occasional flyer or flopper. If you've ever had this problem, you know it's frustrating, mainly because it seems uncontrollable. This is also why I won't even give the ZX5 a consideration (and they're too long). The only T200 downsides for me are the offset from the 7-4 iron and the gapping. The gapping is fixable if you're okay with loft adjustments. So why did I buy ZX7s if I liked the T200s? Well, I saw them and really liked them and then put in a lowball bid on eBay on an almost-new set and the seller actually accepted.
Srixon ZX7 -
I have currently been playing these and also REALLY like these clubs. They're oddly forgiving for being players irons. Like it shouldn't be allowed for Brooks Koepka to play these. They feel great and the feedback is fantastic. They're obviously more workable but with that, I've had a slight issue with control. This could be me getting used to them and they do have heavier shafts in them than my T200s. However, I constantly have the same debate in my head on which ones I should play. Other than my recent inconsistent play, they're everything I want in an iron - more traditional lofting, forged, forgiveness, less offset, good feedback. I plan on playing these for a few more rounds and if I feel like I'm still too inconsistent, I'll switch back to the T200s.
So maybe go a similar route and just dedicate some time to figuring out which is better for you? For me, I just know I can fall back on the T200 if the ZX7s don't pan out and it sounds like you can do the same. Titleist also just revealed a new T200 and T100(s) so that could also be another option on the table.
