I would put him above Grill depending on your needs. I haven't been impressed with Grill at all. Either he just had a below average year for him, or that is who he is. I know he's got some talent, but I'm not sure he has put it all together yet and maybe he never will.
Grill is a high effort player. He's made some great steals and assists this year. Yeah, he gets cold from beyond the arc- just like the rest of the team. Don't know what else you want from the kid.
