Textile jackets cover a huge range of specialized use, differing types of textile, differently prepared textiles, and differing layer position. just checked, I have 15 jackets alone, never mind the pants. Included in that are non textile jackets, 2 leather, and 1 waxed cotton.
One must think about different performance characteristics in the different type of textiles out there. I'm not going to cover Kevlar in this, unless it comes up, as I consider it a fabric unto it's own quite separate in performance levels to all the textiles.
Right off the bat, you need to understand the 1st distinction in a waterproof jacket, whether the waterproof barrier is an inside liner or the outside main textile. I've got lots of both types. If you've ever walked into a hotel room or home, and your jacket weight 20 pounds more in water, and creates a puddle under where it's hanging, you know that's a jacket with the waterproof aspect on the inside. You will find you will have to pull over to the side of the road to put in the liner [riding into a rain storm] and in turn pulling it out [riding down from a cool pass into a hot valley] . Outside layer waterproof aspect is by far superior in basic design.
Types of textile treatment make a big difference in performance, crash capability, and ability. Polyurethane coated nylon is by far the least expensive, and if you fall and skid, IS the one which will melt, and melt into your skin from abrasion heat. Non polyurethane coated textile, almost always Goretex brand Cordura, will prevent this. Unfortunately, this means you'll mostly have to put up with fiddling around with waterproof liner on a tour.
Color. Another thing to think about. Just like helmets, a black jacket will heat up way more in the sunshine of summer. And quickly cool off in the shade. But a lighter color will show dead bug guts in the front, rear chain oil spray on your back, which won't wash out.
Armour. lower cost jackets will have armour less willing to form to you, causing pressure points that will drive you nuts. Study armour types.
Ryan @ Fortine has just done a video basically testing the different textile fabric out there, although not all, and rating them. Quite informative.

What do I use right now? BMW has chosen to make their own fabric [typical Germans] probably to avoid the huge copyright agreement costs of Gortex. It's made by Sholler, a kind of Gortex/Kevlar hybrid, on 2 of their jackets, BMW Streetguard, BMW Streetguard Long, and BMW Enduroguard, which offers the durability of equivalent 1000 denier Gortex, and the ability to make a jacket with the waterproof aspect outside layer #1. I've owned the Streetguard for 12 years now, and only just a couple years ago it began to lose it's waterproof capabilities. And i've gained some weight and it's gotten a bit tight in the belly, lolol. Last spring after deciding it's comfort, venting, etc was the best I've ever had [including a 70km/hr 'off' skidding along my right shoulder and elbow with no rips or wear through's] meant i was going to go with a new Streetguard Long [longer cut on the back preventing cold air going up the back on a sportbike]. The new Enduroguard caught my eye, bought it instead. After a year of ownership, I regret not sticking with the Streetguard. The Enduroguard, much like my Motoport Ultra 1000, I'm sure I'd easily survive a grizzly attack if wearing the thing. That's perhaps it's biggest issue, it's just TOO heavy duty. My buddy has an Aerostitch Roadcrafter, and he says this kind of beast needs a couple seasons to break in. Plus i miss the soft leather neck liner of the Streetguard, the easy to open when riding zippered lower arm/wrist flaps which work as the most incredible air scoops during hot weather, the fantastic venting in front, high quality mouldable armour, yeah, the Streetguard is 'it' even now.
