Ideally you want all speakers in your home theatre setup aimed at the listeners. The ideal way to achieve this is with bookshelf speakers mounted on-ceiling with an appropriate bracket to aim them exactly where they need to be.
A good alternative is outdoor speakers as they are shaped to fit flush to the ceiling and come with brackets. I have just done this to my room - see bottom of this post for more info.
Using bookshelf speakers also allows you to get a closer match to your ear level speakers. There is a lot of debate whether this is important or not, but I believe the closer to identical you can have all your speakers, the better it should sound. However this is often impractical, expensive or aesthetically unacceptable. So I will add this piece of advise :
Use the best, and best matching, speakers you can afford, justify, install and like the looks of.
If that means $75 Monoprice then go for it and enjoy, just don't go listen to a higher end setup because "What the Ears hear not, the Heart craves not"
Please feel free to add any speakers you know of that I have missed - please post the manufacturers link and I can just paste it straight to this post.
But if you must use in-ceilings then 45deg angled baffle is the best for a x.x.2 and x.x.4 setup, As you can see from below they are expensive but there are 30 and 15deg ones available.
Straight down-firing in-ceilings should be avoided at all costs as you can see by this drawing with 90deg dispersion straight down-firing puts the MLP out of that dispersion area :
Unfortunately angled baffle in-ceilings are few and far between. So I just did a quick Duck-Duck-Go search and this is what I found (all prices are for single speaker and some angles are best guesses from pics or drawings since not all manufacturers list the actual angle) :
45deg :

And now to what I think might be the ideal Atmos height speaker : Kicker KB6 $75ea
I have 8" Wharfedale PA speakers all round in my 7.1.4 setup, but I wanted to add front wides and 2 more heights, but the Wharfedales are too expensive new ($300AUD each) and none have come up recently secondhand. So I started looking for something comparable with a compression driver tweeter and the only things I could find was Behringer PK108 PA speakers or no-name brand PAs, but even they are expensive here.
Then I came across Kicker KB6 / KB6000 outdoor / marine speakers with CD tweeters and 6.5" woofers. They retail here for $150AUD ($150USD a pair in the States) but I scored 4 from a pawn broker for $150.
Just finished testing them and they sound great, and as expected with a CD they have no trouble playing loud.
Being an outdoor speaker they are compact(ish) and come with a bracket for easy fixing to the ceiling and easy aiming to perfect spot.
I am a big fan of having all identical speakers but after replacing my 4 4" bookshelf height speakers with the 8" Wharfedale PAs, I didn't notice as much of an improvement as I expected so I am prepared to run non-identical heights, and these mean I can afford to get another 2 to make it 6
