I was fortunate in having a quad of the GEC KT88s. Amazing tube. Even with close to 1500hr they were still the best of the KT88s and overall my favorite. Next, to my ears, were the reissue Tung-Sol 7581a. Not quite the gravitas in the bass, but such a magical mid-range for voices & acoustic music. No tube sounds less than "very good". As you said, a very solid and delightful machine that worked well all the power tubes I tried when bias was set accordingly.
