OK, so you are asking for a brush to use mainly with creams. In that case if you are prepared to spend up to £50, you won't go wrong with a Vulfix 2234. If that's too much you could consider an Edwin Jagger Best Badger - either medium or large are good value in the £25 - £35 range.

You can buy both direct from the makers or shop around for the best price. Here are links to the makers websites.

And if you want a custom made brush, get someone to make you a brush using one of these knots set to a loft of 52 mm.

If you stay with creams and make lather in a bowl and paint it on in to and fro motions you would never need another brush. But now you are here and browsing you will be unusual if you stuck to that.
I've just seen that have started with palmolive cream and the soap stick.
In that case, I still think that the 404 badger/boar brush is your best bet. It will always be a good standby for soaps and do a good job with your cream. Plenty of time to upgrade later.
