They do a fraction of the data manipulation options available from pipes and they require connectors being custom developed, plus they limit you on result delivery, which cannot be pulled.
No those don't do at all what pipe did. First of all, everything needs development. Secondly, webhooks and all that stuff are push only.
The real value of pipes was to pull data out from any compatible client. Wonderful for processing data and have it pulled from a feed reader, not so as a trigger engine, for that zapier abd ifttt are better, but to straight out pulling data from a reader processing websites on demand, none of those could replace pipes.
