I have used both..... My KTM SDGT came with Angel GT's. They were fine once I dropped them from 36&42psi

to 34psiF & 36psiR (light bike big horsepower

). They had good grip and cornered well, and lasted 15,000kms (9k miles) with tread slightly above the wear indicator's (I am a road ST rider, not a track star

).
Next set were R5's running the same pressures and they were much better. More grip, better feel, and they had more tread left at 15k kms (but that was a service and tyre change point ready for a big trip so I didn't run them to max wear - probably 17k kms estimated). R5's have kevlar belt construction so they run cooler than tyres with steel belt construction...... so they get more miles..... but they might not warm up fast enough for cold wet climates or suit track day riding as they are a sport touring tyre

.
The Angels are a good tyre, but can wear out fast if you do a lot of straight up riding. The Road 5's are better at everything and last the full 15k kms even if you don't do much full lean cornering. Sport tyres will have better grip etc but won't last as long if that is a priority so it all depends on what you need for your riding style/conditions.
I'd say for sports touring, the R5 is top of the list.
I think most tyre manufacturer's have caught up to Michelin and all are good for sports touring wear & grip, so it's a safe bet any new tyre will be better than the Angel GT (unless they also have been upgraded like Pirelli did with the Scorpion Trail II, which are a decent tyre now on the V4MS compared to forum comments about the original Scorpion Trail I's -

I'm not so sure now whether I'll change to R5 Trails or stay with Scorp's on the V4MS when the time comes.......).
Maybe chase the best price. Tyres are all good these days.
