I have not noticed a degradation in Claude, but I feel that with Gemini 2.5 Pro.

Apparently the "bugs" only affected some users... which in itself is kind of worrisome... I suspect the changes they made to limit abusers might have been misclassifying some "good" users. Like shadow throttling. This is just a suspicion based on possibly coincidental timing though.

I've not felt it with Claude. Gemini becomes slow and unresponsive at times. However Cursor routinely turns into a toddler banging on the keyboard. God forbid I press the tab key to move a line, lest Cursor deletes some CSS classes halfway down the file.
