Backup app data and restore across ROMs
Restoring across different ROMs, have you considered the "troubleshooting options" of TB, and e.g. enabled its migration mode, or have it using the system's own SQLite libs instead of TiBus? All those things are especially for cases as described with your question. So making use of those might end your search for an alternative; they've always worked for me – migrating from my HTC Wildfire via Motorola Milestone 2 to finally LG Optimus 4X.

If you insist on alternatives, however, I'd suggest you take a look at the backup tag-wiki, where you find many of them described. With Android 4+, you could e.g. make use of adb backup (or use Helium Backup on your device, which does the same locally). Again: This and more is described in the mentioned tag-wiki.
