I have a Viparspectra KS3000 in my 3x3 tent.
It's been good to me and it provides enough DLI but it's DLI everything?
I'm looking to upgrade for my 3x3 space.
That is if an upgrade would help me get bigger thicker buds?
Is it just DLI or is it the quality of the light also every bit as important?
Any suggestions for a higher quality 3x3 light?

Per Bugbee, the quality (color) of a light shapes the plant, the amount of light drives growth.
If you want larger buds that are more dense, the main impediment using this light will be the reluctance to turn up the crop size dial. The light has a fair amount of blue in it and the PPFD map shows that there's not a huge amount of light fall off as you move to the edges. Having said that, the main driver of bud size and density (beside genetics) is the amount of light that the plant gets over the course of the grow.
This is the spectrum for your light:
And the PPFD map (I could not find the hang height on the web site)
I have started to use ChatGPT extensively to improve my growing processes, among other things. My grow is on day 30 and I'm using a Mars Blue 55 light along with my Growcraft X3 flower light. In two days, I'll be adding a pair of Spider GlowR80's. Over the course of the grow, I'll be reducing the run time of the Blue 55's and increasing the run time of the R80's according to the lighting plan that I've worked out with GPT.
With that experience in mind, I ran a session with ChatGPT and it's available
at this link.
In that chat, I specify the Mars RB30 lights because those are the ones that will fit in your light. I have the Mars Blue 55 and the Spider GlowR80 because I bought them at different times. If I were buying supplemental lights again, I'd got with the Mars. The supplemental lights are all pretty much the same but having all of the lights from one vendor means that they will all fit in the same mounting bracket. Mine don't and it's a bit of a PITA.
The chat session has a lot of information that I hope you find helpful with your grow.
The Mars ADLite will help but the biggest step is to take advantage of the equipment that you've already got and turn up the PPFD. Of course, there is no requirement to give a cannabis plant much more than about 70µmol of light. On the other hand, it's impossible for a plant to reach its genetic potential unless it's given enough food.
BTW, with auto flowers, the die is cast on Day 0. With a limited duration for the vegetative state, it's impossible to make up for lost time. I'll probably be switching back to autoflowers after my current photoperiod grow and I will follow the same lighting schedule for my autos as I am for my current photoperiod grow.
Why so much light? Because it's impossible for a plant to reach its genetic potential unless it's given enough food.
