Everyone prefers a different grip, wether it's mid size, corded, there's so many to choose from
I like the MMC + 4 with 2 wraps but currently have the tour360 White with 2 wraps on my 718 AP2
Go to a pro shop to check what you prefer before buying.

For what it's worth, I like my Golf Pride MCC grips ... in black and red colour theme ... of course! ;) I would definitely put them on my next set of irons too!

Ive got Lamkin R.E.L'S in Midsize on all of my clubs and love them. That style of Lamkin has been my grip of choice for a good few years now.

But it depends on what you like to feel from a grip? Some people liked corded grips, full cords, half cords etc, multi material grips. Its all about personal preference

I use the golf pride MCC+4 in Grey, they are expensive but really good due to the taper, would really recommend.

That's quite a personal thing so I would try out as many as you can and make sure they're the right size.
My preference are Golf Pride multi compound in red & black. I like the velvet cord under the top hand.

Guys,
Thanks for the feed back.

White and black multi compound for me !

I recommend that you go for a fitting. Do you want a plain round or a reminder grip? Then you need to consider the feel etc.
How big are your hands/fingers?
Do you need extra tape under one or both hands?
Thick grips..fade...thin grips..draw...they alter your hand action.
If you go to a half decent professional they should have several different grip 'fittings' already fitted to interchangeable shafts and should be willing to help you experiment.
