As FWBO (Friends of the Western Buddhist Order), Triratna had something of a chequered history. Google "FWBO Files" for more information. The spiritual head of the FWBO, Sangharakshita, who was the centre of past controversy is now an old man, and I believe he isn't particularly active in terms of setting current and future direction for the organisation. Furthermore, many of the centres are decentralised in terms of their local management.
For these reasons, I wouldn't give a blanket recommendation or warning about any particular Triratna centre, other than to go see for yourself whether it seems fit for purpose, and to see for yourself whether it seems legit. What they are attempting to do, i.e. present the Dhamma in a manner acceptable to Western culture, is a noble endeavour and whilst they have made some mistakes along the way, that's part of the learning curve for a new(ish) spiritual organisation with big plans.

"The uprooting of identity is seen by the noble ones as pleasurable; but this contradicts what the whole world sees." (Snp 3.12)
“One to whom it might occur, ‘I’m a woman’ or ‘I’m a man’. Or ‘I’m anything at all’— Is fit for Mara to address.” (SN 5.2)
