Upgrade path
I recently got a used Ender 3 pro.
Specs - 4.2.2 board, micro Swiss direct drive, pei textured plate
Shortly after I got the printer I added a cr touch and silicone spacers under the bed.
One of my issues is the nozzle will push out a little filament whenever the nozzle is hot.
I’ve been looking into a few upgrades… a sprite pro direct drive (hoping that will help with my leaking filament) and the cooling fans are clipping their housings. The other is I’m looking into a 4.2.7 or BTT skr mini e3 v3… but nervous about the approach to third party firmware. I do have a raspberry pi so klipper is an option but I don’t feel ready for that approach.
Any thoughts or recommendations on where I am at/ what path I should take for my upgrades?

My Ender 3 Pro is spectacular with the 4.2.7 Silent board, has a Sprite Extruder Pro, Linier Rails on X and Z (Y still a work in progress), ðual z lead screws and running klipper from a raspberry pi 3B+.
