The problem with super simple carbs is that while it may be simple to make them richer or leaner, it is impossible to get them to meter correctly at the full range of operating conditions a street bike is faced with.

An S&S works best when a thunder jet is added and bleeds are manipulated in order to give it an effective additional metering circuit. Simple is nice, but only if it works as good as not so simple.

The Lectron, EI, lake injector, etc. all can work great at Wfo. They are all to crude to be close to ideal in a street application.

Simple carbs appeal most to folks that are afraid to get lost in the shuffle of tuning a multi circuit carb. That task is not rocket science and almost anyone can learn to tune carbs. It is a matter of understanding what does what and why and then developing the experience to read your progress as changes are made.

Honestly almost any carb can be made to work, to some degree. Some are better for certain applications, for sure.

you are correct on the lake slider as it best performs on a track. however, they can be made streetable. like any carb, trial and error. the gravity flow is largely controlled by the tapered needle but for the average joe you are probably right, overly complicated even though simple as can be.

Lectron?
+2 Had one on my 1982 FXR and loved it. It was Harleys performance carb back then.

If you by racing mean drag racing, then yes.
As for real racing, with bends, a flat-slide is the only way.

...and I have a 45 HSR and a matching Hammer manifold on the shelf to put on.
