I don't know what is your use case, but for mine Pusher is better by 
definition because it seamlessly supports broadcasting.
So far I'm using it in parallel with google channels for not so important 
events and it looks good. It works through web sockets with fallback to 
flash, but the stats I gather show me that eventually more than 95% of 
users get connected (apprx the same as with google). They have pricing 
model that I like more, fixed price and only one quota (I'm ware of) - 
number of simultaneous connections, lets say 500 ($49), so no hidden costs 
here. I understood the quota is soft, they will ask you to upgrade if 
exceeded. Those connections can be grouped simply by subscribing to any 
number of channels and there is no restriction on number of connections to 
single channel. So all users can be subscribed to one global channel for 
common news, then to room specific channels for scoped messages and finally 
to personal (protected) ones for private messaging. API is very simple, 
java lib is available (simple wrapper for a single urlfetch call). It 
reconnects automatically if network is down and doesn't expire as google 
tokens. There are "web hooks" that can replace google's presence 
notifications. So the 3 reasons I would recommend it are:
1) effortless broadcasting
2) minimum dev effort (I beleive the time spent on channel api problems 
exceeds few years of pusher fee)
3) I bet they are much more responsive as they can not ignore their users 
as Google does
To be fair I don't like flash fallback of Pusher, so this has to be 
mentioned..

In general the fundamental problem of GAE IMHO is that it was rebranded as 
a premium service to justify the costs, which is fine by me as some of the 
features are fantastic, but it doesn't have a corresponding QoS in some of 
the areas and support is not on a level you would expect from a premium 
service.

PS. One final thing I forgot to mention about Channel API problems is that 
it seems some of the users simply can not load the channel javascript lib 
which is hosted by google... What the hell...
