Best UK broker overall? - who is it?

im sure there a mixed opinions on this, but im looking at FX pro and forex.com (there system doesnt work very well on trading view) or onada and traders way

looking for recommendations on experience please

cmc markets has its own platform which includes very small timeframes, like 5s, maybe even 3s, if i remember well. Excellent for scalping. They are also reliable, no problems with withdrawals. Admiral markets also good.
