I like to normally run a 210/115 pairing. I have two set ups with this combination of cabs, Fender Rumble and Ashdown Root Master (RM) EVO II. I like this pairing as the 10s give a bit of natural brightness and punchy lows, while the 15 gives a full deep sound. I also stay with the same brand and series cabs, as they most often are voice to compliment each other. The Ashdowns are in approximately the same price range as the Rumble, or even slightly more, but shouldn't be prohibitively more.

Both are in their respective budget series in their brands. Both sound great in their own way and are light weight. Both series have switchable tweeters. I find they each sound best with their own line of amps, Fender head with Fender cabs, Ashdown heads with Ashdown cabs. The pairings of amp and heads sound descriptions will also be along the lines of the tones of the brands.
To me, the Rumbles are more vintage sounding and are a little bit mid scooped as common to Fender amps (guitar or bass). They are ported cabs and give a looser, deeper low end. The tweeter does give a more modern sound, but they still sound more vintage than the RM cabs. This can give you a pleasant sounding cab solo, but can at times, struggle in the mix, unless you push the mids. They are a little bigger than the RM cabs and have side mounted recessed handles, if that makes a difference. The 115 is actually the same size as the 210, but it's turn 90° on it's side dimensionally. I have seen one cab or the other turned on their side or turned upright to have a matching dimensionally stack. Some have even changed the grill cloth to match the direction of the weave. I have the stock casters on the 115 for easier moving.
The RMs are sealed cabs and are tighter, more articulate sounding. Their voicing is a little more mid to low-mid forward sounding. They are a more modern sounding line than the Rumble cabs. They can sound a little off solo, but stand out nice in a mix without being too "in you face" forward sounding. These cabs are smaller than the Rumbles and the have top, center mounted recessed handles. They stack evenly and have a smaller footprint. Not seen in the picture, I have a small furniture dolly that sits perfectly underneath the cabs to help move them around. I used a pair of 10 foot/3 meter cinch straps to make the stack a little more secure when pushing the stack around.
I like the Rumbles for older styles of music, country, blue or rock/rock and roll. I prefer and use the Ashdowns more often, with more modern sounding blues, rock, country and worship. Both have their own character/sounds. The Ashdowns have a more mid crunch style of sound that I like.
If I need a more modern, neutral/balance to brighter sounding amp, I have a Warwick Gnome I with two of the Duke LeJeune designed 110s.
These are my experiences and tastes. Your mileage will vary.
