I like that it is easy for me as an individual developer, or small team of developers building apps with rails asset pipeline (rails-assets). It's very good solution if you are using multiple gems in one app - because when something changes within gem A then B will automatically change too without manual intervention from our side! There isn't much dislike about this product but rather more positive aspects such us ease management etc., which make my life easier while managing dependencies between various applications/gems developed by myself / other people working at same time. We use different application framework called EmberJS so we have some differences regarding what can be done via javascript code vs server rendering approach used both frameworks together makes things even better than just single technology would do alone!! Managing all js libraries required across several websites built upon Angularjs + ember JS stack made everything simpler since now no.
