With the latest RPi 4 with 8GB ram, with an SSD drive, for my use cases I haven't found the performance problems at all. However I can totally see that for many other use cases performance might be a limiting factor.
I also considered going with NUC earlier, but because RPi is very "standard" it is very no-hassle to set up, and internet is full of different tutorials etc.
I just hope that in the future they also launch some premium & beefy version of RPi, so you could use all the same software etc but have more performance.
