what is interesting - how that will affect a competition (pricewise).
An interesting question, yes! There are a couple of other plug-in suites that come to mind from onOne
. Also AKVIS.
Nik/Google offers (6) plug-ins for $150 (discount available); onOne (7) for $200 (occasional discount available); Topaz (10) for $300 (15% discount available) and AKVIS (18) for $468 and up.
You'd have to line them up and make a comparison chart to be exactly sure but there is some overlap and some uniqueness among the sets.
I was surprised to see Google actually not only re-release the Nik plug-ins but charge for them (albeit a much lower price). I understand they weren't really updated, just rebranded, which raises a bit of a red flag (this would have been a great opportunity to kick them up a notch). They promise further development, but one has to wait to see. Between the future uncertainty due to the nature of Google and the questionable TOS, I wouldn't fully trust them.
