Proguard alternatives

Is there anything better than proguard outthere? Doesn’t have to be free.
In my search, I found this Semantic Designs: Source Code Obfuscators
Anyone know some other options and perhaps have had some experience?

specially for apps: DexGuard | Saikoa

Thanks. Adding another one to the pile - APK Protect–Android APK Security Protection/Encryption/Guard, Better Than ProGuard & DexGuard
