Hoping to help people make their choices correctly (great idea of topic!):
(I've grown two of them next to each other)
Royal Bluematic (-Sa 10% In 60% Ru 30%- autoflower) from
Royal Queen Seeds:
Healthy plant, smells citrusy. High was disappointing, I would NOT recommend this strain (thus no picture). The high was almost "absent"? Maybe that was a fluke, although the plants looked amazing and frosty. Airy/fluffy buds.
Royal AK automatic (-Sa 35% In 40% Ru 25%- autoflower) from
Royal Queen Seeds:


That one was much better than the Royal Bluematic, it smelled fruity (like mixed fruit juice, close to peach maybe?). The high felt more in the head than in the body. You'd smoke this and laugh, feel comfortable. You cannot focus much with it and so I'd recommend this strain to watch a funny movie, or after a tough day and need to unwind the frustration. Buds were fluffy, not so much airy. (They were not packed like you'd expect an indica)
Special Kush #1 (-Sa 20% In 80%- photoperiod) from
Royal Queen Seeds:

This strain gave me the most quantity, huge plants, easy to grow (the first to sprout, the biggest ones also as you can see on the picture). Smells citrusy. High was normal, I'd rate it 5/10. Its not more in the head or more in body, a bit of both and not
particularly enjoyable. Overall I was disappointed, it's not a quality strain, more of a quantity strain. Buds were fluffy, open, airy. (I haven't grown sativa 100% but I'd say it was halfway between indica and sativa)
Bubble Kush (-Sa 20% In 80%- photoperiod) from
Royal Queen Seeds:

So this is the winner hands down. I'd rate it 8/10. (10/10 for me and my problems of anxiety -for daytime use-). It's much more of a body stone, it calmed me down and it wasn't making me laugh in particular. A lazy strain for the first two weeks, but once I grew accustomed to it, I wouldn't need to smoke more or add more, I would
function normally and be calm (had forgot how it felt). Still need something even stronger for insomnia. (so much interested in the GG mentioned above haha).
Buds were much more tight than any of the others, easier to trim according to me. I could see the Indica in it, compared to the others.

(photo taken from seedfinder, but mine looked exactly like that)
The smell is not easy to describe, I'm pretty sure it was a myrcen terpene dominant though (I should smell hops to confirm that haha), with a hint of pepper in the background.
Good luck getting angry while high on this strain, it's almost impossible.
I loved it so much I started growing the autoflower version this year, will update this post with the autoflower version once it's harvested and smoked.
