I would have to agree that you need to develop an eye and watch a lot of films and go to a bunch of museums. You can't work on films and not be able to talk about them. You also find inspiration in other art forms. So a broad understanding of art is great. If you want an over view ... the story of art is a great read. And if your starting to color, you should be learning how to match grade. Single most important skill that will get you working on more projects.
I've graded on resolve, lustre, baselight, and some other smaller platforms. Resolve and baselight have similiar tool sets. My opinion is they only differ at advanced levels. if all your doing is banging on lift/ gama/gain until you have a good image and then keying skin tone and adding a vignette ... you can do it on any platform. If you want to recreate a style of image like a 2-strip look or something that looks like it was run through a telecine with the coring over cranked, you need flexibility in your tool set and I use the same show lut for every film. So the looks I create are done by manipulating the image layer by layer. The layer system is what makes baselight stand apart. Similar to oil painting, you broad stroke lower layers and fine tune higher layers. Building subtle adjustments layer by layer. I think baselight offers those tools with more depth, flexibility, and overall larger set of options. Plus is aces color science and implementation blows the rest out of the water.
All my pontificating aside, it's a matter of comfort and personal preference. I may find doing something in resolve cumbersome but someone else might think the same process in baselight is cumbersome.
So I guess ... you can split the diff.
