It's a nightmare out there.
Flash is STILL the most stable version, and I'm sticking to it untill html5 has caught up.
The best performing two browsers on the market right now is still chrome and firefox, and both running flash.
- sure chrome is more speedy then firefox, however it's also one of the most unsafe browsers there is. Except for IE/edge..
*Not just counting in that Google uses chrome as a direct spying tool for everything you do
(
no tinfoil, conspiracy, paranoia intented here...)
You may wonder where I have these results from, and it's fair for you to question it.
I am in the IT world, and linked to several colleagues that work for both Adobe, Microsoft and various other big and smaller media firms.
They do regular benchmarks and general tests of the browser performances and in-dept analysing.
Some of these test results are public and you can simply google it, some are NOT due to company policies.
Ofcourse everything is relative to your own setup, what system your using, specs, ram, cpu, graphicscard, drivers, internet connection, but also what you have running in processors/services etc.
Browser plugins play a huge role too, as well using vpn or not..
I can even tell you that, if you for example disable 50 percent of microsoft telemetry data services - you gain a further more speed upgrade of atleast 10 percent.
(we tried this on windows 10, basically disabling everything onedrive / updates / xbox / apps / and the background services related)
It made every game handle better, and in general enhanced the experience. Browser games included.

Telemetry is an automated communications process by which measurements and other data are collected at remote or inaccessible points and transmitted to receiving equipment for monitoring.
Microsoft has done this since their very first release, and tons of other companies does it too. The constant flow of data slows you down a bit, not much but ENOUGH to make a slight difference.
