A rich friend has let me use all of his Leica M Mount lenses for a while (he's gone digital) so I've tried them all. In my opinion they are all wonderful but my true favorite all-purpose lens is probably the least popular here: The 1990's version of the lowly Summilux 50/f1.4.
Thomas Pastorello wrote this about the lens:
"I believe the current Summilux-M 50 Non-ASPH IS the best
lens Leica (or for that matter anyone) ever made. In
addition to its two main attributes of near absolute
freedom from flare and a signature bokeh of subtle
beauty, it is characterized by an artistic balance of
high resolution and realistic contrast -- even wide
open. It is perfectly balanced on the M body, such
that hand-holding is easy at 1/4 -- which makes it
very fast indeed at f1.4 (more so than the less well
balanced and holdable Noctilux at f1.0).
Will the new Summilux-M 50 ASPH have higher
contrast and resolution than the current? Of course
-- no need to wait for the Puts report! If all I
wanted was the highest possible (and most useless)
resolution and contrast, all I'd have to do is slap an
adapter and a process lens on any camera body. If the
new Summilux-M 50 ASPH has the look and feel of most
other new Leica ASPH lenses, with harsh bokeh and
flare proneness, I will not buy. To learn about flare
and bokeh, I'll have to look at reports other than
Puts'." Tom
And "Feli" on the LUG wrote this about the 'Lux 50 Non-ASPH:
"I've had mine for almost a year now and it's really grown on me.
Not as sharp as the current Cron, which I also have, but plenty sharp.
By f8 the Lux is very sharp, all the way into the corners. I love the
extra
stop and the ability to focus as close as 70 cm. My biggest complaint is
the collapsible hood, which can't be locked into place. I solved that
problem
with a metal screw-in hood from Contax.
But what I really like about this lens is the fingerprint. It's magic
in black
and white. People talk about the Leica glow, and this one has it in
spades.
Buttersmooth tones with the smoothest bokeh and actually quite sharp.
It has a very classic look, hires and medium contrast, which isn't
surprising
given it's lineage, the Xenon, Summarit and first gen. Lux.
I've made some 11x14 prints on Agfa FB Classic from APX100 negs
(Rodinal)
and there is something about the look that even laymen notice.
The Lux gets knocked a lot because it was in production for about 40
years,
and remained unchanged, but it's much better than people think.
Absolute sharpness
isn't everything. Plenty of people made better shots than any of us
could manage with
the 1.5/50 Sonnar and the Lux blows that lens away. In any case, it's
another brush
in the shooters arsenal."

You can still by one of these Summilux 50/f 1.4 lenses in black new USA from certain dealers like Popflash.photo (Tony Rose) for under $1,300.00 which is quite a deal!
