Not using a MSP, but an Acer R7 which also uses a stylus pen.
Works well for PS and LR for my 24mp and 36mp files with 16GB or RAM on board and SSD.
The stylus is good in the sense that it gives the feel/intuition of a pen, but TBH, it can be done via a mouse too or a stylus+pad.
Whats nice is that I don't need to have more table space to setup a mouse or stylus+pad (eg. in a cafe, etc)
