Full Bear upgrade and considering swapping hotend

I bought Full Bear upgrade kit for my MK3S, think I have another week or so before it arrives. Thought process: if it was worth the extra cash, upgrade the hotend and parts when I install the rails 

I've had great prints with the MK3S and have no complaints. To those who have upgraded the hotend and parts neeeded, did you see a big improvement in the prints to justify it? I hear more about the E3D Volcano and the  Mosquito more than others. Looks like both kits are more than a couple hunderd dollars. Just wondering to those who have upgraded was it worth doing considering the cash/time installing/configs afterwards?

Hasn’t arrived yet. Something held up on the shipping, early next week I’m told.

Depending on what you want to print, there are different ways to upgrade the printer. For standard applications a well adjusted original MK3 with the original brass nozzles and extruder is perfectly sufficient.
What I would possibly improve is to change from linear bearings to sintered bearings for the X and Y axes with better and more precise mounts and maybe 0.9 stepper. The frame construction of my printer is still original.
I have also installed a modified Bondtech extruder version on my printer. Here an example of a print (black Extrudr ASA):

I appreciate the reply. I can't send you a pm (post count?), can you give me some links on sintered bearings, mounts and .9 step motor? I am interested in that. Also the Bondtech extruder?

About 0.9 Stepper and Bondtech Extruder there are enough posts here in the forum. You can find posts about the sinter bearings and their mounting in the German speaking forum: https://forum.prusaprinters.org/forum/original-prusa-i3-mk3-hilfe-zur-hardware-firmware-und-software/kreischender-drucker/paged/11/#post-234532

This refers to these bearings: https://www.amazon.de/Turmberg3D-Sinterbronze-Gleitlager-12-Zylinderform/dp/B07D25BLCX

I built this extruder for my printer, but this is still the version with the Misumi bearings. There you would have to adjust the mount for the sinter bearings, but that shouldn't be a problem.
