Agree absolutely phil, I was brought up the same way (I just turned 70 the other day, I still can't believe it!).
But just as you say, if one wants a particular tool (or anything else virtually) there's all the difference between a tradesman buying to work his/her tools daily to earn a living and someone like me who is in reality, "just fiddling around enjoying himself", (as my lovely lady says, "It's better than hanging around wasting money in the pub every night"). And another consideration in my case, with no one to leave an expensive "tools legacy" to either.
Normally, over here (Switzerland) things that I see on this Forum as being available in Lidl/Aldi UK appear here soon afterwards (sometimes even before they appear on this Forum) but in this particular case - multi tools - they didn't appear in either until a long time after I'd bought my green Bosch, and the only other choices then were blue Bosch and Fein (as I wanted mains rather than a battery tool). I don't regret that choice, though I do recognise that the Fein is a much better tool - probably the blue Bosch too.
As always though, there is a BUT: In another thread also in this section, but about Router collets, I explained a problem I was having re a collet to accept bits with 12.7 mm shafts. The (cheapo, "badge engineering") manufacturer was of no help at all with that, and it was only members of this Forum that got me successfully sorted out with an available collet to suit, a process that was complicated, frustrating and time-consuming. OTOH, that extra collet was a LOT cheaper than buying a new Router just to take 12.7 mm bits, which was the only choice I thought I was facing at one stage.
But again OTOH, both Aldi and Lidl have long guarantees on their stuff, and from all reports seen on this Forum, they handle those guarantees in a no-quibble fashion. So I guess if one thinks one may need "customer support" like I did, rather than "simple refund/replacement", then one should at least go for a "name brand".
Not an easy decision sometimes.
