In brief:

I enjoyed Biomutant & would recommend it, but I don't think it's worth the full price...
I'd recommend holding out for it to go on sale.
It's a gorgeous world with engaging characters & fun mechanics. Good-not-great story. Lot of choices, yet limited outcomes. But many small problems/annoyances that can stack up.
In more depth?
I think there are a lot of positives, and I clearly enjoyed the game enough to play it through completely - but there is a very real sense of incompleteness at points.
The environments are beautiful, even gorgeous at times.
The world is worth exploring and can really pull you in.
The major named non-player characters are fun to meet and have their own quest-lines (which I wish were longer, but enjoyed).
There are lots of fun mechanics to play around with.
Many mounts are just variants of one another, but several are unique/fun in their own rights. Even so - I spent most of the game running on foot (erm, or all fours, I suppose).
The main story-line feels a little simplistic, but was fun/engaging enough. Without spoilers, I will say it improved a bit towards the end - but I still feel like there were some missed opportunities.
Many side-quests won't allow progression until more of the story is completed, but the game won't necessarily inform you of this... Just direct you to places where objectives can't be completed at the time. Which can be frustrating, but you learn to expect/anticipate.
The combat system took me some time to get used to, but as I learned it I did come to enjoy it. That said? Once learned, is does feel repetitive. In theory this is augmented by the variety of weaponry & skills, but...practically? There's a very limited number of weapon-skills per weapon. Also, there's a handful of gear in the top-tiers that you'll end up (likely/presumably) favoring - and, as necessary, deconstructing/rebuilding with better parts. There's not a TON of casting/bio-abilities, either. So...variable styles of play, but not a ton of selections.
Most of the puzzles are simple affairs that will only be challenging if you don't invest some skill-points in intelligence. That said, a couple/few feel insufficiently explained (you'll still work them out, but it's a little frustrating). Also? The puzzles feel like they lose a lot of their weight/importance in that the consequence for failing is minor damage and waiting a few seconds to try again.
The third-person camera isn't the worst I've seen, but it can/will be problematic at points (from managing to obscure itself in the environment during combat - to preventing the player from gauging the height/scale-ability of a mountain). It even landed inside one of the world-bosses (Porky Puff) during a battle, almost getting me killed.
Several locations glitched for me (and other players) after the initial clearing. Example: Guppo Grotto's elevator is intended to be reusable, but the door glitched on me and wouldn't let me interact with it (workaround was going backwards through an earlier pipe using creative jumping/items/skills). Another example would be certain mobs failing to respawn as intended (more frustrating re certain achievements than limiting game-completion).
Also - I found some invisible walls that seem unintentional at one point -specifically Punkle Peak's island not allowing one to completely circle it.
And 1 of the (I believe 14) Fluff-Hulk locations isn't tagged/indicated on the map. If you're doing the side-quest connected to the keys they carry, it will still give you an idea of the area... But here's the (spoiler blocked) general location: 10M
Ah, and I managed to get 100% of the game's achievements in ~84 hours. Which isn't horrible, but pales in comparison to many games at a similar price-point.
Again - I enjoyed the game, but it does feel like an incomplete (or insufficiently polished) product, and thus only worth buying on a (preferably steep) discount.
