So, Mesa calls for all 6L6 in the 395 but I recall seeing people doing something with other tube types...more research needed.
Also, the 395 is SimulClass, which does effect the feel IME and the general consensus. A little more "bubbly"/not-quite-as-stiff.
SIMUL 395
The 395 uses four 6L6's per channel in our unique and patented Simul-Class™ circuit. The
Simul 395 - weighing in at 95 watts per side - boasts a smooth, mysterious and liquid
response that many players find captivating for lead playing. This is the seductive
smouldering Simul-Class sound with its uniquely vocal quality. Rear-panel Class A switches
- a hold-over from the Simul 295 - reduce power by cutting off one pair of output tubes,
though you may prefer the somewhat similar sounding Half Drive function on the front. Even
though the 395's major talent lies in its trademark Simul howl, its clean sound is crisp and
bright with plenty of headroom for even the biggest clubs.

The Strategy 500, at just under 200 watts per side, is the world's most three-dimensional
sounding musical amplifier. The 500 uses four 6L6's plus two 6550's in each channel. Its
shimmering clarity and bright dynamic headroom make it the choice for players
concentrating on their clean sound ... or playing the biggest venues. This amp is fast, punchy
and bold! And it’s greater articulation enables it to be layered with effects and still retain a
focused sound.
I agree mostly with how Mesa is describing how there power amps sound in the manuals.
