They may seem like it. But, no they do not.
Bangladesh pitches are more dry, slow and low in bounce compared to UAE. They turn more than Dubai and Abu Dhabi.
They deteriorate as the match progresses. Making it difficult for batters to get a hold on the surface's slow turn and spinners.
UAE pitches, specially Abu Dhabi and Dubai offers movement with the new ball under lights to pacers.
Dew has a much bigger role to play in matches. In the last half of the 2nd innings. It becomes difficult for spinners to grip the wet ball. Which is not the case usually in Bangladesh.
UAE pitches are more balanced. In fact I think they are one of the few pitches. Dubai and Abu Dhabi specially that offer everything to everyone and you usually see scores between 160 to 180 between two good teams.
Bangladesh are more spin friendly pitches because of the driness and slowness of the pitch. 140 becomes a winning total. There's no dew or not much when compared to UAE.
