Which Border Crossing is best?

My plans have changed for the Rocky Mountaineer group in July and I will arriving with the group and having the time as holiday whilst they are cruising. I can’t afford the crazy prices in the Vancouver area so I am going into Washington State. There is a choice of 4 crossings but can anyone suggest which is best?

My plan is to cross on a Sunday at the end of June before Canada Day and although I will have both an ETA and an ESTA am aware that I will be taken aside to be legally entered after purchasing a I94.  I think the information in regard to arriving into the States by land is hard to find and it is only my experience at the Rainbow Bridge at Niagara Falls that has prepared me for this visit. I anticipate a delay to my journey but can someone give me the best choice?

From West to East

Peace Arch

Pacific Highway or Truck Crossing

Lyndon/Aldergrove

Sumas/Abbotsford

I recognise Peach Arch from the Border Security programme on the television but unfamiliar with the others.
