This was by far one of the best animes I've watched but it is not everyone's cup of tea. If you are not bothered by a protagonist who never loses and don't consider an incestuous relationship as a taboo then I would definitely recommend you watch this.
Though it is set in the future the conditions are well thought of and the scenario is quite practical if you give it a thought
This anime tends to be descriptive way often then not but if you are a fan of the sci-fi genre this will surely not disappoint you because the explanations are well thought off. Having read 16 light novels till now I haven't found anything that disobeys the laws of physics based on the explanations given.
Overall I will rate this anime 10 mainly because there is a lot of homework done on the setting and the protagonist though seriously overpowered doesn't come of as an arrogant and bad persoon
