Sky vs Vodafone vs Plusnet 500mb broadband

Hi which out of the 3 would be best and likely to have the lowest rises with inflation in April? does Sky still let you cancel if they increase the price in April

prices all very similar
Sky 35
Plusnet 34.99
Vodafone 32.00

Can get Fibrus 1 900mb for £40.00 but lots of people seem to have issues with xbox game pass so it put me off it
