More in-depth thoughts on making the switch to csp? I’ve been debating it for a good while now and would love a secondary opinion! Also thoughts on having to use new brushes after the switch? <3

I'd been using krita since 2012, so it felt like i'd be cheating on it if i switched to csp. I think it was a combination of the fact that i know krita very well by now, plus i had made a whole bunch of pens on there and i'm pretty sure i can't bring them with me to csp, etc. oh and also the fact that krita is free. That was major for me, because i grew up without a lot of money and so i learned to work around getting expensive art supplies and such

However... Csp is totally worth it. It's been a process figuring out the set up and configurations, because it's not as simplified as krita (though krita has these same tools, some of them are different in either program. Some things are just two clicks in krita, and take longer in csp, while other things are a fifteen step process and krita, and csp already has an entire docker there waiting for you). But it's not too hard and it's fairly easy to look up anything i have questions about. They would be tied when it comes to set up, if not for the fact that csp has set ups ready to go for comics that feels a lot easier to work with. So that's win 1 for csp

Win 2 for csp was the brushes and stamps, etc that are on there. It takes a lot of getting used to, and i'm not a fan of the stabilization so far (not exactly sure if there is another option yet, but from what i can tell, individual brushes have stabilization options. Not bad, until i struggle to find an overall stabilization option, if there is one). In krita you can just hit "E" and it will turn whatever brush you're using into an eraser with the same texture and settings as the brush, and pressing "E" again turns it back. But in csp, erasers are limited and i don't like them very much.

But!! Texture,,, i'm a big fan of the everything else about the brushes. it kind of feels like working with actual physical materials (as much as it can). Watercolor mixes and acts like it's on real paper, etc etc. i'm really liking the pens that i found (because in csp, you really should be using the assets page to find brushes, or look up tutorials to make your own, but the default brushes are still amazing if you don't want to adventure out!). Krita is very limited on these. Csp sort of gives the effect of physical media and texture, whereas krita always has a digital look to it. If that makes sense? I'm not saying csp doesn't look digital, but it just has way more of that oomph that i've been wanting for my art for years now

All in all, i can say that i still recommend Krita, especially for beginners, and especially for people who can't afford to spend money on a program. It's still a VERY good place to draw and i'll likely still use it. It's a great starter and honestly, you don't have to make a change if you like it. But csp is also very much worth the money and you won't regret it
