If you will pardon the pun. I am in the same boat.
I really like the idea of SH4. But you are absolutely right. There is "something" not right with SH4. It is tough to put my finger on it though.
I do know, that for me, manual targeting in SH4 is more awkward than in SH3
I am getting ready to start up a new career in SH4, but I am sure I will be back to SH3 very soon.
