Hasegawa AH-64D, Are Accessories An Overkill?

Hi all

I've decided(against my own better financial advisement) to buy a "real" helicopter kit, the Hasegawa AH-64D (1/48).

I've seen that Eduard has an interior detailset for the D model and Aires had a replacement cockpit set.

If I got both would that be overkill or would they compliment each other?

If one will do which one is the better option?

Lastly, does the kit really need accessories or is it pretty good straight oob?

Thanks
John
