| Aspect | LightStanza | Other Revit Plugin | 
| Multi-Calculations | Run multiple calcs simultaneously without slowing Revit workflow | One calculation at a time, locking user out | 
| Calculation Reliability | Reliable calc engine | Complex calculations prone to crashing | 
| History and Comparisons | Calculation history and design comparisons | Difficult to compare different design options | 
| Large BIM Models | Calculate large BIM models without reducing scope | Frequent scoping to manage crashes and calculation times | 
| User Interface | Easily navigated and learned (3-hour training) | Requires significant Revit expertise (8+ hours training) | 
| Revit Model Impact | No extra data added to your Revit model | Extra sheets, views, objects increase project file sizes | 
| Loading Speed | Regular Revit loading and operation speed | Increased data load slows model operations and load time | 
| Data Integrity | No data lost when syncing to BIM | Syncing on same project loses calculation data | 
| Collaboration | No issues for people working on the same model | Potential conflicts with syncing to BIM 360 | 
| Model Flexibility | Freedom to edit/fix the Revit model without affecting original | Stuck with existing Revit model | 
| IES Files | Various linear lengths use a single IES file | Each linear length needs a unique IES file | 
| Collaboration Type | Online collaboration | Traditional (e.g. email attachments) |
