I don't have incubator stats... nor do I have a good way to measure "most
active" or "most successful" projects in the ASF (seems that itself could
be a 'centithread'-worthy discussion). But a potential proxy could be the
number of stars on github:
https://github.com/search?utf8=%E2%9C%93&q=user%3Aapache&type=Repositories&ref=searchresults
 (sort by number of stars)

Of the top ten:

Spark: RTC via github pull request
Storm: RTC (https://storm.apache.org/documentation/BYLAWS.html see "Code
Change")
Cassandra: RTC (based on my skimming the commit log which has "Reviewed by"
quite often)
CouchDB: RTC (http://couchdb.apache.org/bylaws.html see "RTC" section)
Kafka: RTC (based on "Reviewed by" showing up in recent commit logs)
Thrift: CTR
Mesos: RTC (based on reviewboard links in most of the recent commits)
Zookeeper: RTC (based on personal experience and comments above in this
thread)
Cordova: CTR (based on
https://github.com/apache/cordova-coho/blob/master/docs/committer-workflow.md
)
Hadoop: RTC (based on personal experience)

Briefly looking through the #11 through #30 projects I also see a
substantial number which operate on RTC (and others for which I don't know)

So, I don't think there's much evidence that RTC prevents a project from
becoming successful in the eyes of the developer community. Also worth
noting that several of these are relatively new TLPs (i.e. within the last
~3 years) whereas others are quite old but still active and successful.
