Style is entirely subjective so not relevant to the bargain thread.
For me I've had no issue with Endura quality or fit, I believe they have a decent reputation.
I don't have a ton of their kit, but do like their mitts, have a few of the older design FS260 shorts when they used to come with different width pads, and have some of their top line jerseys in both short and long sleeves, which are really top notch, both in terms of material feel and quality, and the fit.
I suspect if they don't fit you, it would just be that your body shape isn't compatible with their dimensions that they use - we all have brands where certain items simply do not fit, for me it's Giro helmets, and Pactimo shorts - straps are too long.
Never tried Le Col so can't comment on them, Castelli and Ale tend to be my two most utilised brands.
Avidly disagree on Sigma, I'd say they have some items at very decent prices, and still have reasonable sales - let's be honest, competition is relatively scarce, surely no one knowingly shops at anything owned by mike ashley these days.
We're VERY restricted now in the UK to where we shop for online items with a reasonable range and price, for me Merlin and Sigma are good and always have been, both in terms of choice, price and customer service.
Where would you shop instead of Sigma then, and what Le Col bib short equals the Castelli Endurance 3 for £78?
