Spline is so much fun. If you never wanted to touch 3DS Max because it looked too scary/complex -- then give Spline a chance. It feels like very Sketch/Figma-ish and it really is just fun playing around with materials and the properties.
Having played around this week again (not with the beta, but the 'stable' version) I do see that it crashes quite, quite often. It'll auto-save, so it's fine, but something to keep in mind (Could also be the M1 version I'm using)
Oh, yes, instead of just drawing something I found it much more motivating to just import any (not too complex) SVG you may have (like your company logo!) and then start modifying that in 3D.
