Yes, it is. The difference is big enough that anyone who is optimizing, and I really need to point that out because of course people who don't care or don't know any better will still play other races (wonder where we could find some of those), will always pick Dwarf. Dwarves had one disadvantage from being the go-to choice for Str/Wis (I concede, you actually need to make use of the Con, so Fighter have to get Plate... gee darn) and Str/Con classes (and Con/Wis, Wrath Invoker had Dwarf as a Gold option. Gee, when the stats line up, Dwarves are a Gold choice... funny, that seems somehow relevant), that disadvantage no longer exists.
So, to recap: Top tier choice with one of the most serious disadvantages, accuracy on attacks taken during your turn. Serious disadvantage: Gone. Other things: Unchanged. What do you call something that was almost a default choice that got better? The default choice.
And, again, this only applies from an optimization perspective. I don't care what unoptimal builds people want to trot out and say they are going to play, that doesn't prove anything.
