I know this is asking a lot of investment for a throw-away thread, but check out some of the casts here,

After you watch a couple of those, I'm pretty sure you'll be in a good position to judge effectively.
Saying that, from the videos Ive watched, I would judge Starcraft 2 to be less strategic than one. There have been a lot more macro wins, a lot more times where people win every encounter but lose overall and a lot more clust**** fights. The strategy is still intense but a little less so. Saying that, Starcraft 2 is still newso the strategy hasn't got oodles deeper than pump ou thte correct counter-units, like it did eventually in 1.
In the end i comes down to difficulty settings. Games with low difficulty can be won with unit spam, competitive games require you to be more devious. It's the same with a lot of things in life, from Squash to FPS'.
The only other problem with RTS' is I find there's a large barrier to overcome before your planning and clicking skills can enable you to take the strategy higher than unit spam. Pros can click at 200 times a minute and this frees them up for strategy
EDIT: Found a great example, just 12 minutes and shows what a skilled player can do to a player with a little less skill. http://www.youtube.com/user/HDstarcraft#p/u/4/dxsJaPT14uM
