Doesn't matter, as long as you bleed them properly and make sure theres no air in the system. 
You might need to do each side more than once.

Typically the caliper furthest away from the master cylinder is recommended to be bled first on any vehicle.
In you case that would be the left caliper first, remember to keep the master cylinder reservoir topped up during the procedure, often forgotten when engrossed in the bleeding process.
As Andy says you may have to do each side more than once.

Are you on the original caliper seals?

They ingress dust 'n' dirt after a while, a full caliper strip & clean up would restore them to original spec, but it's NOT an easy (or clean) job to do if you know little about brakes

Braided lines are the way forwards.
You can try tying the brake lever back with string or a cable tie and leave for a while, preferably overnight, it's helped firm my brakes up before.

Braided lines are okay but not a be all and end all. You lose so much feel

Aye, you lose that spongy feel, and get a nice responsive feel. Much better, knowing extra pressure is creating extra braking, and not expanding the lines a bit more!

I find that the more responsive the brakes feel the more respect you give them, but all in the knowledge that if you need to grab them in an emergency then the bike will stop.
I ride a lot in traffic up close to other vehicles so having sharp braking, and knowing exactly what they're going to do is very important for me.

Put a clear hose on the nipple and a container for the fluid to go into,then make sure the brake res has fluid pump it a few times then hold in on, then undo the nipple and close it (while holding the lever in) then pump again a few times and repeat the process until it bites, don't let the res empty of fluid always keep it topped up. Just keep doing this until u get rid of any air bubbles u can see in the clear hose.

I find this a lot with braided hoses.
 
What works for me is to connect a 50ml syringe and clear hose to the bleed nipple, pull the fluid through the system until the master cylinder can push it through by its self. Works every time.

I personally just loosen the screws and unsettle the lid, just make sure you don't forget to do it back up before moving the bike.
Stick something on the seat as a reminder so you don't end up with fluid everywhere!

There's 2 tiny holes either side of the reservoir lid that will expel fluid (even with the reservoir lid screwed tight) if you tie the lever up and there's slightly too much fluid in so wrap a rag around the lever/ master cylinder/ reservoir area if tying the lever over night.
Not much worse than coming down and finding there's been brake fluid on your paint work for the last 10 hours slowly eating away!
Some say...
