Question for MEA players on PC:

I have a Logitech G700s with about 7 extra buttons. Never felt the need to use them for this game. Only thing I've changed is hotkeying Ops Pack to Q.

I'm using the same. It is a very good mouse and very tunable to suit your needs, whatever they may be. I was using Cyborg RAT7 that has a bunch of nice features and actually feels better in my hand but it had a couple glitches after about a year and it is not as tunable as the Logitech. Logitech, IMO, makes the stuff that qualifies as "best bang for your buck".

That thing looks uncomfortable. Those gaps and pokey edges don't bother you guys?

If you are a "Claw Grip" style of mouse player i would highly recommend these 2 mouses they are superb in comfort and ease of use:

Logitech G302
This mouse is the successor to my Razer Abyssus and im loving it very responsive fast and so comfortable specially if your using a claw grip or a mixture of claw and Palm grip style since the back side of the mouse is rounded in such a way it grips really well see pics on google. Because it uses "Omron" switches i expect it to last longer then the Razer one.

Razer Abyssus
(older version NOT the version 2) that i used for years which is really good (comfort, tactile feedback, response) the only CON they tend to break fast comparing to other mouses. This one has a similar rounding at the back side as the G302.

Both mouses are relative cheap but great bang for the money.

It is truly important that you pick a mouse that fits "naturally" or rather feels really good in your hand for hours and hours of play time. It depends on your hand size and how you use your mouse ie: "Claw grip, "Palm grip" i would recommend watching youtube in order to see the difference in grips and what mouse you think is good for you.

If you're talking about the G502, no. It's one of the most comfortable mice I've ever used; unless you have large hands or sausage fingers, you'll never come into contact with any of the pokey bits.

What I can do is advise AGAINST certain mouses from experience. R.A.T. 7 or anything really from Saitek/Mad Catz. Razer Deathadder, and by extension anything from Razer. So yeah don't buy any of those.

EDIT: seeing a lot of people recommending Razer garbo, that's fine everyone has their opinions. My opinion is that with Razer you're making a "bet" you could get a good one or you could get a piece of trash like mine (by all means, check reviews on the internet, they are quite mixed when it comes to Razer).
Since we're at it: the RAT line of mouses is notorious for 2 things: being expensive AF and being a flimsy piece of trash. Last time I checked reviews on Amazon 90% of the people said that their mouses started to malfunction or brake altogether withing months.

Well. I am not sure I can recommend it, but I've used my mouse for the last 5 years and it is still going strong!

Wait, can you use mouse + keyboard to play on the PS4?
If so, does it have raw and linear input or it just converts the signal to act as thumbsticks?

I really wanted to go with the Logitech G502 but unfortunately in looking it up, apparently it isn't compatible with the Hori Tac Pro :/

Anyone have an opinion on the Razer Naga? A buddy of mine recommended that one. Thanks for all the info! I'm still reading through all the replies.

Even if reviews say stuff like that, my advice would be to just have some runs with the mouse that comes with the Hori Tac Pro and see if it's really that bad. According to the tech specs it's a 3200dpi optical mouse, so it should be able to handle itself.

If you feel it isn't working out, then go for another mouse from one of the brands already mentioned but just keep the original mouse's tech specs in mind. You may also want to check if another mouse is compatible with the Hori Tac Pro set in the sense of functionality: you may well buy a mouse with a gazillion programmable buttons but if the Hori Tac Pro software doesn't give you the option to actually program them, you'd obviously be wasting money.

Last piece of advice: don't select a mouse with too many loose parts, since they do break or fall off eventually. Hope that helps!

I use this mouse as well and love it.  You should know, however, that it is by design a heavy mouse.  Due to its weight, I would only recommend using a hard surface pad as you may find it drags too much on cloth.  It's designed for a right handed hybrid claw/palm grip.
