Just gave RGT cycling a go, and did the Cap Formentor Route. I liked the realism, both in scenery and ‘handling’ - your wee doppelganger slows for hairpins and roundabouts - and although it was odd cycling on such deserted virtual roads, I guess that’s far more akin to real life too. It was a great route too - I can definitely see the appeal in doing it IRL 
Downsides: it was a lot jerkier than Zwift, even on medium graphics; that’s perhaps because I had to run it on an old, crappy iPhone rather than my much newer (and now dead) Samsung. It also chewed through 60% of the battery life in about 75 minutes, which caused internet drop outs as the phone got critical; I had to eventually stop, get off the bike and plug the phone in (unfortunately out of reach).
Most annoying was the gear changing, which isn’t entirely RGT’s fault. The major downside of a Wattbike is that the gears are push buttons with little tactile action; you don’t get any feel for a gear change until the resistance itself changes, and you’re reliant on the app you’re using to tell you what virtual gear you’re actually in. Zwift talks to the Wattbike and tells me what gear I’m in (1-22) but RGT hasn’t enabled that, so I was having to watch my power & cadence as a proxy for the gear I’m in, and mentally count changes too. Not ideal by any means!
Overall, I enjoyed it a lot but I doubt I’ll use it that often; Zwift seems more versatile and is better suited to my trainer. That said, I’ll definitely give Mont Ventoux a go, and will be keeping an eye on it for new and exciting routes
