I almost agree; but in my experience, JetBrains IDEs are worth every cent. I am more productive on them than in Visual Studio Code, even for "simple" tasks, like raw HTML/CSS/JS editing.
I’m flipping between Jetbrains and VS code a bit, but Jetbrains is by far the superior experience.
If you're going to roll Jetbrains then the more RAM the better and a good CPU also helps.
Obviously, this means MacBooks that aren't fully kitted out are bad picks.
In my experience, the lazy autocomplete takes less resources at start but the result is that autocomplete suggestions are loaded in as files are being parsed. The larger projects grow, the slower this process is.
I suppose slower CPUs like the i3 series and low i5 series Intel chips will probably have a lot of trouble with the indexing. You need a laptop with a decent sustained core speed to do the work (which can be a major deal breaker in cheap Windows laptops and the lower tier Macbooks), but the few seconds wait you get on a professional machine when a project gets loaded in is well worth the wait to me.
VS has now mostly caught up with their feature set, and the only thing I miss is namespace refactoring (which I could implement myself with Roslyn.)
Is R# just an exception, perf-wise, to their track record?
Shitting on tools because you read a couple disgruntled comments about indexing without honestly evaluating the tool yourself says a lot.
