Ive driven/owned cars with the semi manual thing where you take it out of drive and tap the gear shift and it switches... Those usually work really slow or not well at all. My dads GTI has that and it workd decently well.
And paddle shifters are a pain in the ***. Too hard to reach them when turning if they are attached to the steering column. And if they are attached to the wheel itself, when its turned a bunch of ways and you're trying to shift because you're driving fast through some turns its hard to remember which is which, because the shift up may be on the left side depending on how far the wheel is turned.
Both kinda ****. Id either just get a regular manual or an auto. Really only true advantage to a manual is it gets better gas mileage.
