Are you enjoying riding the bike as it is? If so keep riding it.
This!
I had low-spec forks on my hard tail. I rode the ass out of them (there was only room for a small ass in each leg, obviously!

) for about 1500 miles, then upgraded when they started to leak and the lock-out wouldn't hold reliably.
If you like the way the bike rides, why listen to anyone else's opinion. There is always someone who will tell you there is something "better" out there but, well, so what? If you like the current set up, then nuts to those who are wanting to spend your money for you.
Here's a thought for you. I've got an early Yamaha Fazer 1000, it's over 10 years old now and has 40k miles on the clock. When they first came out, the bikes were heavily criticised by the press and those who read more than they rode as having poor suspension. However, I never really found it an issue, so I kept going on the standard set up. Finally, after over 35k miles, the rear unit was going off badly, not that it was dangerous but it was telling me that it had served its time carrying me, luggage and pillion, so I went to the local specialist to get new (and rather lovely!) rear suspension fitted. I had a word with the chap there about the front suspension, said I was happy with it but asked if he'd check it out and see if there was anything that needed sorting. He went out for a ride and came back asking what work I'd had done to the front end, saying that most new bikes would struggle to match the way it felt there was little that he'd want to change about it. He was shocked (see what I did there? **groan**) that it was the original unit, completely standard and having been there for the life of the bike.
You know how the Dart 2 shocks feel to you, for your weight, for your riding style on the trails you ride. Sometimes, the armchair reviewers just get it wrong.
