Northern for me -
158s - solid, overall nice trains. Still feel modern for their age. Best BREL DMU I think.
170s - nice modern era DMU's, shame about acceleration though.
323s - Comfy, speedy and reliable, great motors, still look and feel modern. I can't complain.
319s - I like the seats and the motor sounds, but the reliability is a ? mark though. Mind you what did they expect when they have had no mechanical work or enhancements done on them (at least not that I know of)
156s - A bit noisy, but I don't mind them too much.
150s - Noisy, slow but have better seats than the Civity so goes above it
195/331 - look cheap & old fashioned to me, not very well styled at all very basic for a new train.
153s - are everything that is wrong with our railway and shows an era of underinvestment, compromise, grime and sluggishness.
If a 319 turns up. Reliability has been poor, since they arrived to Northern in 2015. Won't beat a 3-car 323 in terms of acceleration and capacity, though.
What is so unreliable on a 319 as I've heard many people slating the relaibility without actually saying what goes wrong on them.
