Re: shade/hospitality
I think Tafraoute has a different vibe to many other places due to being touristy, and a lot of the crags there face south. But, further north, things were peaceful, the people were lovely and very kind and welcoming, and there are many north- and east-facing crags.
Re: quality of climbing/quartzite, etc.
On big routes, there were definitely some less good pitches, but having repeatedly tried to convince a friend of the quality of climbing on offer, here are just a few almost random climbs with a real line off the top of my head:
Reach for the Stars, E3 5c: 40m vertical handcrack.
Poet's Corner, E1 5b: 50m excellent bridging up a huge corner.
Marrakesh Express, E1 5b: climbing up a distinctive rib via slabs and cracks.
Scimitar Ridge, VS 5a: a gradually steepening 300m ridge line with a funky pitch through a roof and a fantastic arete on the penultimate/final pitch.
Spitfire Tongue, E2 5b: up a distinctive corner crack and then the wall above.
Sahara, VS 4b, and Jedi Grooves, HVS 5b: lovely open face climbing up a pillar, then two pitches up an exposed, narrow ramp/groove system.
Brisingr, HVS 5b: an intro pitch and short wall lead to a fantastic 40m pitch up a technical bridging corner, before an exposed groove pitch.
There were other great pitches that I did over two shortish trips, but many, many more striking lines that I looked at with longing and didn't get done: cracks, aretes, corners, slabs. On the first trip I was there with people climbing harder, and remember looking over to them climbing E3 - E4s in outrageous positions.
I did do some overrated pitches... including one that got 3 stars but was dirty, loose, poorly protected and uneven in difficulty. But, I felt I got a three-star route done every day of my last trip, and when I came back to the UK I felt disappointed for a while by the comparison.
