To CuriousArtemis/MMG's point comparing with Anders... hmmm, I think the relative development and content is debateable. Many folks find the Solas romance to be a desert with tiny, too infrequent oases of awesomeness. Esp compared to the woo-break-ful Cullen romance. So, ymmv. The "dammit, Solas" reaction is also all over the board. But again... agree: WORTH. IT.
Sooooo worth it. And now I'll go throw myself back into the abyss of angsty feelsuh. 
Well for Anders there are two major cut scenes (he has no romance-related Act 3 cut scene) and with Solas there are three, so already Solas wins 
But mostly what I meant was that DAI is so much longer, and Solas is such an integral part to that story. DA2 is incredibly short, and Anders is fairly peripheral until that final scene.
Regarding fans who are complaining about Solas not having enough romance scenes... stuff and nonsense
It's quality over quantity, and again, Solas is probably the most important companion, yes, even more important than Cassandra (who would have predicted that?!). Now I romanced Iron Bull, and there were several romance-specific cut scenes, but I barely remember them because they were mostly just about sex and humor. (I wish I could burn from my mind that awful scene where the couple are "interrupted" by all the advisors....)
Now I haven't romance Cullen, so for all I know there could be like 5 high quality deeply emotional cut scenes lol so in that sense I guess he would be rivaling Solas, but again, Solas is so integral to the story... plus his romance is very SPECIFIC since it's Lavellan-only; how many other romances refer REPEATEDLY to your race and culture (but not gender, ha, THANK THE CREATORS, I mean, er, f*ck, who am I supposed to pray to now?!)
