The SD EX's are good HG-style builds particularly for those who are just getting started with Gunpla. They introduce you to real-application Gunpla building, but with fewer parts and an easier overall build as to not be overwhelming. The biggest drawback is the stickers. While some details in this model are designed-on, most are applicable with stickers. Stickers are great for those who are just learning, or not serious Gunpla freaks, but they do cheapen the build if you use them. Top-coating and linework still works well on these models!
