Tough choice. Both do completely different things. Guardian is a tech monster with his utility and high sig. King Groot is a healing beast in the cosmic class. Based on what you need, you should make your choice.
Guardian King Groot for me has only been useful in Robot matchups
King Groot is useful in so many match ups, he’s got easy and permanent armor breaks, bleed immune, power control immune, decent poison damage, insane regen, and destroys robots. I use him frequently in BG as both and attacker and a defender. He’s so tanky with his high Hp, healing, and shrugging debuffs.

Not to mention book 2 of story content bias basically made for him
If u need a champ for BGs or for AW prowess meta, Guardian is the easy choice..... he's an extremely good Tech champ
If these 2 aren't priority then may be KingGroot bcoz he might not be the fastest but has a lot to offer & doesn't need as much sig investment as Guardian
Guardian is the faster attacker in most cases but KG is probably the most sustainable champ in the game Both have their own sets of utilities so can't really compare on same standards
Choice will come down to the type of content that u need the champ for & availability of sig stones

If not, King Groot.
