'schlecht' and 'suboptimal' can both express that something is not good enough. 'schlecht' is direct and clearly negative. 'suboptimal' sounds more cautious, more polite, or sometimes ironic. It means that a solution, result, or situation is not the best and has shortcomings. In conversations about planning, work, or problems, 'suboptimal' can sound softer than 'schlecht'. If you want to say directly that something really is not good, 'schlecht' fits better.
