The OP isn't comparing backhoe to no backhoe.
The suggestion is that he comparing a BX23S with backhoe to an L2502 without a backhoe. None of his listed tasks require a backhoe, a number of them would greatly benefit from an L sized machine.
He says he already outsources serious excavator work.
Given the constraints he provides, I'd say an L class machine is a better choice. If the OP can stretch to an L with a backhoe, great. But that's a lot more than a BX23S with a backhoe.
