You look awesome in both sets of pics, I say do whatever makes you the most happy.
From a guys angle, I can totally see where your hubby would like the slightly heavier (softer) you, us guys really do like a softer looking women lots of times! that's not to say that a tighter more physically fit (in appearance) women doesn't look great too. I wouldn't imagine that its too much of an issue with him though as as I said (and lots of others in this thread) ya look great in both and any fella would be glad to walk around with you on their arm
Us guys really not as picky as you ladies think most times lol.
As Ever
