which exact touring bike is gonna be something only you personally figure out, since touring involves spending a lot of time on a bike, fit is especially important.
that said, one consideration is what sort of touring you're doing? there's credit card touring, where you pack lightly with essentials, then pay for shit you need as you go along, like hotels/meals. for this youd get a light touring bike, or just not even a touring bike but some sort of endurance road bike that can take racks.
then there's your traditional self sustained touring where youre bringing everything you need with you, tent, supplies, food, spare parts. this is where you get a dedicated touring bike. the burlyness of that bike depends on what sort of terrain you're touring across and how long of a tour it is.
then theres the combo of the two, bikepacking, where you take some mtb/dummy thicc road bike packed with supplies and fuck off innawoods for a weekend. its still self sustained, but you pack light since its a short tour
tl;dr figure out what kind of touring you're doing, then what bike does that the best
if you want an easy point of comparison, look at treks touring lineup. the 520, 720, 920, and 1120. all touring bikes but made for different types of touring
