I don't see how you could go wrong with sRGB, ntil the day more people are looking at the web through wide gamut displays, be it tablets or monitors.

The Lab we expect is the default Lab from Photoshop, which I think is D50. So, what is the best choice for RGB space? We are tagging the files, and prefer v2 profiles for more browser compatibility, but will do v4 is needed. I don't need help in the transformation - I just want to know the best RGB space to present the widest gamut resembling Lab as possible. I assume one of the best choices is Don's MaxRGB? http://www.hutchcolor.com/profiles.html I welcome any input!

My userbase commonly has full Adobe RGB coverage monitors - creative professionals. So maybe that’s the choice? - J

IF everything is color managed, Adobe RGB (1998) is fine. If it isn’t color managed, it will still look reasonably good on a wide gamut display, awful on an sRGB gamut display. The opposite is seen with sRGB (OK on sRGB gamut display, not on wide gamut display). So if again, everything is color managed (the image data and browser) AND your audience is using wide gamut displays, you gain nothing with sRGB and a bit wider gamut from the original in Adobe RGB (1998). Or DCI-P3 (6 of one, half dozen of the other). Andrew Rodney http://www.digitaldog.net/

IF.?. Sounds like assumptions are still big in play. Henry Davis

Indeed, there’s a big world of non color management in terms of browsers (although less so), some require users to turn on color management (Dumb). Some folks are still working on old operating systems with really old browsers. Now the Jeff did mention briefly his target audience and perhaps (IF again), they are all using color managed browsers. Only Jeff can tell us for sure. Andrew Rodney http://www.digitaldog.net/
My creative users will be using modern browsers with color management and wider gamut displays like Eizo, ASUS pro-graphics (both sRGB and Adobe), BenQs (Adobe), and iMacs (presumably P3). All calibrated to 2.2gamma, D65, and 120cm2. We will have occasional business users on old PCs and older browsers but I need to serve the former’s needs, not the latter’s. I’m considering creating untagged sRGB fallbacks for everything and allow the user to choose in a preference but that’s expensive resource wise. - J
