what do you think of this engine compared with a7?

its has a great editor, cool scripting, lots of features..

a7 also have great features but a bad scripte editor... without auto-code-completion. this is the thing i am missing very much..

did anybody compare Shive, DX studio and A7?
i am looking for a great solution for me..

i am a code and want to program a lot. therefore i need a good editor and a good engine
