paclite is like lace compared to 3L pro. If you're hard on gear, it'll rip or tear in no time.
The hardshells like 3L Gore Pro are super fkn durable as well as tough. Softshells are less weather resistant but generally softer and more comfy. Lightweight rain shells like paclite are more for ounce-counting weenie climbers and such, as they generally won't hold up to beatings and bushwhacking.
I personally love Norrona. I have a full 3L Gore Tex Proshell onezie and can honestly say it's the sickest piece of gear I've ever seen, heard of or used. Talk about bomber! Arc'Teryx is nice but I've owned a few pieces and it is a SUPER athletic fit. I do still have a pair of stinger softshell pants that I've had for like 5 years though and they are tough. I like Norrona better though. Better fit, better colors, more designs. Never had an issue with quality or durability either.
I would say DEFINITELY upgrade to a hardshell- the most layers and highest quality you can afford. I wouldn't worry so much about whether or not it's "gore", as there are some amazing fabrics out there now, but if you're looking for a shell to last you years and years and years and still protect you, go multi-layer hardshell without a doubt. Norrona, Arc'Teryx, Rab, Mammut and Patagonia are all companies I'd try to look at first as well.
