I thought I had impenetrable walls in my last flat. Bought a big fuck off SDS+ drill to compensate. Turns out I just had shit masonry bits. With good bits, my battery combi drill with it's "hammer" setting was just fine. Although, the SDS+ drill was fine too, just overkill.
I did just get a new set of bosch ones. But anything newer with a decent, sharper (masonry aren't really sharp) point/t-section will be better. But it doesn't necessarily rule out fire power upgrades. Just cheaper to try out a new bit before getting a new drill.
