Heather, I am 4 days into Smart Things and it has been pretty great so far. I too moved from Wink to Smart Things. Wink was never really a contender for me, I just tried it because it was cheap with my GE Link Lightbulbs. I can say it was difficult to setup and it stopped working a few times. Their customer service was excellent though. I was strongly considering Revolv because of their ease of use, mostly excellent integrations and awesome tech support. I ended up going with Smart Things, because although they do not officially support everything, they at least allow the community to create smartapps and device code and usually make them work. Revolv locks you out, as does wink and some of the other hubs.
My current setup:
5 GE Link Bulbs
1 Leviton Appliance Switch
1 Aeon Labs Energy Consumption Switch
1 Wemo Insight (not on the system and will be replaced by an Aeon Labs Switch)
1 Sonos Play 1
I plan on getting a Nest and the Nest Protect. I really like the Yale lock; however, I want to see the reception of the Goji and August smartlocks once they are released within the next few months.
The most difficult thing to get running properly is the smart apps that group the GE lightbulbs and allow dimming. I have it almost working perfectly now thanks to the help of @wackware

It’s $100 bucks and you’re heavily invested in tech that will work with it better and more reliably than Wink. I’d say pull the trigger, it’s a no brainier.
Side note: I’m unsure about the dlink IP cam, but i’m pretty sure it would work. I heard there was foscam integration; however, I haven’t messed with mine since getting the Dropcam.
