Only if you are doing it for diversity and fun reasons. From the old days I have a maxed out Ursaring. Although I like him, looking at things objectively I have to say that he is worse than my equally maxed out c/dp machamp in every respect.
It's true that he does not have the same weaknesses as fighting mons, but the additional power of machamp more than makes up for that (ursaring is not particularly bulky anyway). His kill speed in tyranitar raids is also way worse than that of a c/dp machamp.
