Both anime focus on a different pairs that come closer over time and their struggle to come clear with their feelings.
Both anime also have the same strength that the unusual pairings are the more interesting ones while the more normal ones tend to be a bit on the more basic side.
In general you could say if you like one you will probably like the other, because both anime have a very similar feel to it, but Konbini is definitely the weaker one of the two.
