The constant things in these threads is, is there a need to go for the
best
as in specs or best as in value for money

The answer is there isn't one simple answer

No there isn't.

If specs were the be all and end all then why do Makita/Dewalt still
sell
9.6 volt tools when there are higher spec'd 24 volt ones around. Why
do they
make different rated tools in each voltage band, why do some come with
1.3
ah batts when 3.3 ah batts are available

Because for some tools, 9.6v may be enough. For example, I have a
Makita angle driver which is highly geared. This does not need to
turn rapidly but does need good torque, so 9.6v through a gear box is
a suitable approach.

Look. Its all tosh. You can get as much power from a 3v motor as a 300v
motor. You just put less turns of thicker wire on it.

All this 'voltage' ******** comes from the days when you had crappo SUB
C cells that could do about 10 amps a piece at 1.1v roughly. So you HAD
to use more cells to get up the power. Now you can get - as has been
remarked - 3300 mA/h cells that have been clocked at a little short of
100A. So the voltage has become almost irrelevant. In terms of power
production. Of course in terms of competitive marketing to dimwits like
IMM its probably highly relevant. 'Goes up to 11' and all that. :-)

As far as torque goes, that's why god gave us gearboxes.

I am not saying more.
