Welcome to Librarium Online!
I would say yes, but I have no idea what sort of army you should build around him. But as long as you don't take his Dais he's got a much more reasonable price, though still on the pricey side. Perhaps a very fast army that really depends on getting that first turn. But like I said, I just don't know what the list should look like.

at 1500 points no. At 2k maybe. My favorite option is to route him in a raider with wracks so he gets a free pain token
1500...no. 2000...yes. At 1500 and less, he is just too expensive as a deathstar unit. It just takes away from the rest of the army until you go to higher-points games.
Record: Win - Loss - Draw: Hive Fleet Pandora (New) 32-6-6 Space Wolf 7th Co. 52-11-6
Blood Angels 12-4-2 Daemonhunters 20-8-3
Imperial Guards 12-5-2 Daemons 8-3-2
Of course he is.
Calling something competitive is a complete and utter red herring - anything can be considered that if you have a list built to support and coordinate with the unit/model/fish in question.
Taking internet DE list #5 and bolting vect on won't work and thus people will write him off at such a points level.
