[major edit, relaised I was talking about the wrong sort of Drilite in Mk. 1...]
Lightweights like Paclite tend to do well at first but get overwhelmed when the face fabric wets out (which it does more readily on lightweights as they're typically thinner), so on the one hand the Denali will probably breathe a bit better longer term as the face fabric in a heavier jacket like that will maintain some breatahbility for longer, but on the other hand the waterproof/breathable layer itself is less breathable to start with than the Paclite. So I think changing to a Denali will just give you a different sort of dissatisfaction.
If you want something more breathable then eVent is one option (it's simply more breathable at the waterproof/breathable laminate layer). Paramo is another, though the liner makes the garments relatively heavy and bulky: if you'd have a mid layer fleece on underneath anyway a bit of a moot point, but it's a bit of drag in warmer months.
Beyond that, try to reduce the amount of time in waterproofs: soft shells will cope with quite a lot of rain conditions and are vastly more breathable than full-on waterproofs. You'll need a hard shell in prolonged and/or really heavy rain, but for showers and driech a soft-shell is often all you need.
