Mine hasn't been the most reliable tbh, but it could be my fault. I think my next printer will be the Prusa XL with at least 2 toolheads, or whatever the equivalent is when I finally am ready to drop that dough. I think I'll also pay extra for them to build it because, as much fun as it was to build my Mk3s+, I do wonder if some of my performance issues are my fault due to the assembly...
