10 dollars isn't much a month, but by the same token, I hate being tied into the subscription. So far, I feel Lightroom is the best tool for me, the DAM features, coupled with the powerful non destructive edits and plugins, not to mention I get the latest version of PS is quite compelling. I've not see a tool or combination of tools that brings this much power, efficiency to the table.
I really liked how C1 handled my RAW files, I absolutely hated the UI, though I think I can make some changes to that, to ease the pain. The DAM features and plugin support are both wanting.
I'm sticking with LR, because why buy, say C1 and sacrifice a lot of functionality that I'm now getting just to avoid the subscription. I also realize with LR, I can buy the boxed edition. I lose out on PS at that point however.
