Yeah, I really missed Penti when I had to use an iOS device for work for a while.
I'm mostly in a terminal, commonly in vim, where the 'regular keyboard' experience makes text and code editing quite convenient compared to the usual software keyboard suspects. In web forms and the like it's also fairly convenient, one can send move left and then hit repeat until the correct position (or any number of arrow key equivalents for moving rows). I hardly ever move the cursor by pointing somewhere in the text.
It took me something like three weeks to become really fluent in Penti, back in 2017-2018 I think.
