Ulfric gave me 2 badass enchantment Daedric swords on my other character. 1 for siding with him at the meeting (As a member of the stormcloak) with the greybeards and the 2nd one to use the sword to execute General Tullius. I could careless about the home in Windhelm because I'm more of a traveler if anything else.
No other NPC has ever given me an enchantment Daedric weapon or armor so Ulfric did me pretty good

I got two enchanted Daedric swords from him on my first SC playthrough. But I started the CW later in the game so was at a much higher level (actually making/wearing Daedric of my own at the time).
Started much earlier this time, SCs were the first faction I joined and I went to Windhelm straight from Riverwood after escaping Helgen. So my rewards were not as awesome... one Dwarven sword, one enchanted Dwarven sword early on... enchanted Ebony sword at the end to kill Tullius. I actually used the Axe of Eastmarch as a primary weapon in the CW after I became Thane, which I did as soon as the option was available. I had only used 2H weapons up to that point anyway.
I used the two Daedric ones for a while because I was into dual wielding at the time, but mostly the reward weapons tend to end up on a plaque or in a display case after the war is over, so getting something at a lower level doesn't bug me so much.
