Both are excellent helmets. I recommend going to a shop that stocks them to actually try them on. Ari makes different head shapes which I like so you have to get the shape correct for your head. That said, the RQ-X may or may not be the correct head shape, but they will make one that fits well. Also the Arai can be fitted by using different size cheek pads. To get the correct size, I usually remove the cheek pads and go for a snug fit on the rest of the helmet, then get the correct cheek pads. I don't know how the Shoei accommodates shapes and sizes. Personally I go for the lightest weight with best fit. I'd say the construction quality of Arai and Shoei helmets are on par with each other. Hopefully more will post.

My current helmet is Arai RX7-RRV (Corsair V?), last helmet was RX7-RRIV (use it for 5 years).
I always wanted to try Shoei but unfortunately I have an Arai head. I can wear Arai for hours comfortably but 10 minutes in Shoei in the helmet store will give me a headache.
IMHO, if a helmet doesn’t fit your head you can forget about it and move on to another.
I echo what John said. It is not a case of better or worse between those two options. Both are high quality helmets. It comes down to which fits your head better and, as mentioned, Arai makes different shape helmets. If the RX-Q does not fit your head right another model likely will. I personally prefer Arai. To me they are the top helmet on the market. The build quality as well as the design and fit/finish is top notch. That said, they do not cater to the gimicky side of the market. No flip down tinted visors ala Scorpion or Caberg. I wish they did pick up on some of that and hopefully they will because their pin-lock system is nowhere as nice as the flip down visor others offer. Some gimicks actually work well. But the fit and feel of the Arai for me is perfect. But you should try them both and see which you prefer. Leave them on for as long as possible to make it a better test. Some times you find pressure points after 20 or 30 minutes that aren't apparent right away.
I have the RF-1100 (called XR-1100 in Australia) - cannot fault it.
It retails for US$730 here and we need an Australian standards sticker on the back of it here for it to be road legal so cannot buy them cheaper oversaeas.
It comes with a chin curtain and I added the Whisper Strip option which cut down the noise on an already very quiet helmet. The Pinlock system means it has never fogged up and most days have the reactive lens pinlock (Protectint) in - that goes from clear at night to a medium tint during the day. Changing out to the dark smoke pinlock takes about a minute for day only riding.
Maintenance wise, it started to get a bit of a whistle around the visor after about a year of nearly daily use but recentering two screws on either side of the visor made it like new.
The Arai did not fit my head at all. Sounds like it comes down to a question of phrenology and then what graphics you like better.

Hey Phang, where on your head does a Shoei helmet cause a hot/pressure spot? Is it on the sides toward the top?
I'm asking because I've just tried a Shoei RF-1100 at a store, and after 10-15 minutes I started feeling a hot spot in that region - unfortunately, they did not have Arai helmets in stock, so I could not make a direct comparison. My head is roundish in shape. Thanks, Greyo
I recently had the bucks to splurge on an expensive helmet and my first thought was a Shoei so i checked out a few larger accesory outlets that were full of sales people who just wanted to sell a helmet , and i was a bit confused with choice.
I then stumbled across a little shop called Highside Leathers owned by a chatty fellow who it seemed knew what he was talking about and who loathed the larger acessory outlets with a passion. He had both Arai and Shoei in stock, so i tried both on. Both fitted but the Arai felt a little more comfy. I was strongly advised to buy the Arai and when i questioned why he started pulling both helmets apart and showing me how they were made and the quality of the padding. He summed it up by stating that Shoei are made largely for and to suit the US market and standards while the Arai is made for and to suit the tougher European market.
I bought the Arai Italia, the best helmet i have ever owned.
The Shoei (X-11 to be exact) which I’ve tried 6 years ago gave the pressure point to my head exactly at where the thunderbolts pointing and I think I have a round shape skull too.
Both Arai RRIV and RRV are noisy helmets, ear plugs are a must on long distance trip.
