Signergy vs Tesla - Similar prices

In my ongoing solar package quotations, I was pretty much set on my Tesla package but received an offer this morning for SigEnergy. Pricing is pretty much the same for either package:

Option 1

• 22 × AIKO 465 W solar panels
• Tesla Powerwall 3
• Tesla Expansion pack
• Tesla Gateway

Option 2

• 12 kW Sigenergy hybrid inverter
• 3 × 8 kW Sigenergy batteries
• 1 × 5 kW Sigenergy battery (29 kWh total storage)
• Sigenergy gateway
• 22 × AIKO 465 W solar panels

I have purposely added extra battery storage for winter days and future heat pump. The question is here, any advice or reasons to choose one over the other? The one concern that has been flagged to me is Sigenergy warranty, only 5 years for the inverter and some elements, such as the casing, is only 2 years. Tesla also has unlimited cycles.
