Seems like I'm leaning towards this option yes, as the lightning acts as a beltless cross zip rugged tank with a nice patina. But man that pebbly horsehide is also very unique.By themselves, one vs the other, beltless fits better and looks better on you, although I’m not a fan of black teacore, or yellow core in this case.
In the context of your collection, belt seems like the better choice, beltless fits/looks better but lightning looks even better than beltless and the fit on both is pretty close, otoh belt has room to layer, which seems like something you need/want for some occasions.
So imho going with belt would leave you with a tshirt only cross zip (lightning) and one for layering (belt).
If I didn't have 7 leather jackets to rotate already I'd keep both
