At the end of the day, as industries mature, you can, in aggregate, segregate things into a couple of platitudes. You have those products that will absolutely require marketing and promotion to move forward, because incremental progress on a product is not enough alone to move it forward (Think of your average ICE car, how different are they nowadays really? If you take the emotion out of the equation, they're really not too different). Then there will be those that are on the cutting edge frontier, where the action and innovation happens (Again, cars, where there is a different is something like Tesla or the chevy bolt, and that requires a LOT of pure research, development, engineering etc). If you don't like one, you should probably pursue the other. There isn't as much middle ground as things mature. Financial services is another great example of this. Cutting edge privately held funds is where all the quants go because it's interesting (with some exceptions, i'm talking in aggregate), where as your JP Morgans or your Bank of Americas tend to be all about marketing (even on the various other services they provide that you don't usually see TV commercials for, or web ads, or what have you).
