I am in no way qualified to give investment advice. That being said, the issues described above create severe usability issues for the currency. In addition, the slow block times undermine the core value proposition of Bitcoin Cash, which is consistent quick confirmation times and high throughput. On the other hand, a hard fork could pretty easily fix these issues. But my personal opinion to infer that development teams that have made major gaffes are likely to continue making blunders and that digital money requires a high degree of forethought.
