Intel is building their new chips on that microarchitecture so it will probably be fine.
Their bad reputation is fully deserved, it's just also out of date. Reputations are almost always about first impressions, and the first impression with E-cores was bad. They've done a lot to fix the situation though, and they do indeed run pretty well nowadays if you have a more modern Intel CPU.
That said, manually disabling AVX-512 on P-cores just so I can have E-cores is still a *bad* tradeoff as far as I'm concerned, but I get that my use-cases aren't everyone's use-cases.
