Choosing three star E5s is too easy! I’ve focused on E1-E4 and not included anything with three stars.
Wavelength E3 (Bosherston). Excellent route that feels quite remote even though it's 10 minutes from the car park. The chimney/slot can be a bit damp.

https://www.ukclimbing.com/logbook/crags/stackpole_head-791/the_whaler-162576Stackpole Cracks E1 (Stackpole). 27 recorded ascents since 1972. People have no taste! Definitive two star E1. Very tidal.

Reach for the Sky E3 (Trevellan). Not that reachy but good technical climbing.
https://www.ukclimbing.com/logbook/crags/trevallen_cliff-710/reach_for_the_sky-24901Run Wild E1 (Buckspool Down). 3D roof followed by techy slab. Quite bold if you go straight up the middle of the slab.

Well this has had less than 50 recorded ascents so relatively obscure. I didn't think E3 as some comments suggest, the top crack is a bit awkward but only HVS.
No Man’s Land E4 (St Govan’s). As above. Like two V2/3s at your favourite indoor wall, soft for E4.
https://www.ukclimbing.com/logbook/crags/st_govans_head-7/no_mans_land-24799The Gong E1. (Madman’s Point.) Not that off-piste as it has a couple of photos in the select which have just nudged into the 3 figures of recorded ascents. Good steep fun on huge holds. The Madhatter’s Tea Party, similar grade, looks good too but without the musical possibilities. There is a direct second pitch in the supplement that could be used for either.
https://www.ukclimbing.com/logbook/crags/elegug_stacks_bay-23717/the_gong-270772Wet Thread E3. (Raming Hole). Littlejohn, steep, burly, a bit loose, very good.
https://www.ukclimbing.com/logbook/crags/raming_hole_area-794/wet_threat-45204Dragon Slayer E1 (Gun Cliff). Qualified recommendation. I backed off this as it was wet and I was trying to follow the description rather than the photo in the guide. I can usually climb E1s at Pembroke in the wet, the only comments suggest E2 rather than E1. Looks great as far as i got.
https://www.ukclimbing.com/logbook/crags/gun_cliff-793/dragon_slayer-137408Maninwhite E2 (Mowingword). Great rock, fun moves, soft for the grade! Climb it with the evening sun on it ideally.
https://www.ukclimbing.com/logbook/crags/mowing_word-792/maninwhite-355925Olive Branch E4 (Mowingword) looks great as Duncan says and my leader dispatched it smoothly enough for me to leave it for a flash go sometime soon hopefully.
The starred routes on the Mowingword hidden wall (E1-E4) are all good.
