'eigen' and 'komisch' can both mean that something seems strange or unusual. 'komisch' is very common in everyday language and can simply mean: this does not feel normal, or I do not understand it. 'eigen' often sounds a little more cautious or distinctive. It can also mean that something is typical of a person or thing, but in an unusual way. 'komisch' is more direct and can also sound more strongly negative. 'eigen' works well when you find something odd but do not want to express it too harshly.
