WHen the TA-152H was still perked, it had very similar kill numbers, but a substantial higher K/D than the Spitfire XIV. But both planes were far away from all the other perk planes, both in usage & success (K/D). Both suffered (and still do) from similar stability problems, though the Spit is even far more difficult to handle
.
When the 152 was finally unperked, I was amazed they didn't do the same with the XIV.
Since then, the TA has indeed become more popular, but unperking it didn't result in flooding the arena with 152's either.
