Debating to leave my job half way through my contract, what should I do?

I graduated with a computer Science degree in 2016, did a 3 month systems analyst internship in 2017 and in 2018 I got a job as a business analyst. After 5 years as a business analyst I got made redundant exactly a year ago. Took a few months off and went on holiday, then in January of this year I got a new job as a software engineer in the public sector as a 2 year contractor. Over a year in to the job and I am getting frustrated as it feels like there's a lot of micro management and I'm not keen on the environment, there is a new guy that joined the team in the same role as me a few months ago who is around 25 years older than me with way more experience, he can talk forever and is always keen on doing everything and today the project manager of the project that I'm working on has stated that I 'should be more proactive like him', I was a bit annoyed at this and I don't know whether to speak to my line manager about it. I really want to leave and don't know whether to wait for a new role or just leave like this.Will it look bad to my next employer if I left after a year and how do I explain it if asked at interview? From a financial perspective I have nearly 20k saved to keep me going if I decide to leave without having something else lined up.
