Dividend Priority: 

Preference shares receive dividends before common shares, ensuring that preference shareholders are paid first.

Fixed Dividend: 

Preference shares typically offer a fixed dividend, providing consistent income, while ordinary share dividends can vary based on the company's profitability.

Voting Rights: 

Preference shares generally do not come with voting rights, unlike ordinary  shares, which often allow shareholders to vote on corporate matters.

Capital Repayment:

In case of liquidation, preference shareholders are paid before ordinary  shareholders but after debt holders, giving them a higher claim on the company's assets.

Accumulating dividends:

For cumulative preference shares, if the full preference dividend cannot be paid, the unpaid amount will accumulate and still be due in the future. Ordinary shares do not offer this feature; if a dividend is not paid, it does not guarantee higher future dividends.

Voluntary redemptions: 

For callable preference shares, the issuer has the option to redeem (or buy back) shares in the future. This is often done if the issuer can raise new capital at a lower cost. Ordinary shares do not have this option.
