I’ll try T1 variants and Everfree Grayish first, then compare with U4T tactiles. appreciate it

This is interesting. Thanks for posting this.

For MX Clear replacements, I sometimes prefer Durock Medium Tactile. Which is inspired by Zealio V1 / V2. The new Gateron Longjing Tea are somewhat nice, but maybe too gentle for your requirements.

For you, I would recommend some other switches in the Ergo Clear category. The JWK/Durock or JWICK T1 were often rated as being 'better Ergo Clears.' Some interesting variants of the T1 are the SP Star Polaris Purple. Some people prefer the SP Star version of things.

The Everfree Grayish are definitely worth trying, if they are still being sold at budget prices. They are Gateron's attempt at a budget heavy-tactile. You could compare and contrast them with KTT Matcha, which may be too light for you.

Most of the items I just listed, except for Everfree Grayish, probably aren't 'crunchy' enough for you. What some people do is put Durock Medium Tactile stems inside T1 housings. This produces a ramped-up Ergo Clear.

The MMD Princess switches are very, very affordable heavier tactiles, and most people would also try the more upscale U4T tactiles. The Haimu WS Heavy Tactiles are something cheap to experiment with.

People who use them favour the Durock Anubis. Others speak well of the Tecsee Purple Pandas. One of the most tactile switches available, possibly worth trying for you, are the Zeal Clickiez in tactile-mode.
