I totally agree with Prof Tilley on the buildability, so to say, of the
vinylish plastic parts that come with the Dragon kit - these are
definitely not a problem.
I'd also recommend the Dragon Bismarck, but with one caveat - the light
AA guns, particularly the 20mm ones, seem to me to be inferior to those
that come with the Trumpeter kit. Other smaller parts also seem to be
crisper in the Trumpeter kit than in the Dragon kit. Of course one can
always replace the light AA guns with aftermarket items (or get a
Trumpeter kit which might be the cheaper option!).
The main drawback of the Trumpeter Bismarck is in my eyes the way the
deck has been split up in three parts. I couldn't imagine how to put
this together properly without getting seems, so I opted for the Dragon
one instead where the seam of the two-part deck is cleverly hidden
below two secondary barbettes.
By the way, as far as the Tirpitz is concerned, only the Dragon kit
builds into a correct one out of the box - Trumpeter put the same heavy
AA fit into the box as for the Bismarck, which is obviously wrong.
