Perhaps but it depends on your preference. Jay was never all that creative as a rapper. He was more so a traditional emcee who balanced his skill/flow with great beat selection.
Kendrick is more alternative like an Andre 3000 who dropped solo rap albums, a lyrical Kanye, or a mainstream version of Blu.
Kendrick has more acclaim for sure but Jay also has at least 5 albums that can be deemed classic worthy such as Blueprint, RD, Black Album, AG, and 4:44.
And his lows aren't even that bad. Only MCHG is a truly bad album. KC and Blueprint 3 were more so a mixed bag.
But it's apples and oranges because Jay has 13 solo albums while Kendrick only has 6 if you count Section 80. Obviously, it's much easier to stay consistent with a 6 album run than a 13 album run.
And that's not even factoring in the Streets is Watching Soundtrack, his live Unplugged album, and the Jay Elec album he collabed on this decade which were all heat.
I'd argue Jay has higher highs as a well rounded emcee with bars, flows, features, and quotables while Kendrick has higher artistic/musical highs. Apples and oranges.
