I personally was surprised how much the slicer can matter. So perhaps try if Prusa slicer helps here also. Prusa is not better in every regard, but it’s worth a try. That said, I personally suffer - as many who received the Kickstarter version - from a somewhat bumpy print bed. This in my case results in places where the filament is squashed down on the build plate too much, while in other locations it barely sticks. That causes an inconsistent bottom layer quality/look. For me it yet was not that relevant, I get along, but if you also suffer from this, there are many threads here in the forum with suggestions to mitigate the problem. Snapmaker updated the base platform at some point - I’ve no idea if that solves it. I personally plan to at some point use paper washers to compensate for the build platform imperfections.
